+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an

+# is unlikely to handle the host's binaries.
+# Fortunately install-sh will honor a STRIPPROG variable, so we
+# always use install-sh in `make install-strip', and initialize
+# STRIPPROG with the value of the STRIP variable (set by the user).

+\`configure' configures LWTools 3.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR            user executables [EPREFIX/bin]
+  --sbindir=DIR           system admin executables [EPREFIX/sbin]

+  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
+  --libdir=DIR            object code libraries [EPREFIX/lib]
+  --includedir=DIR        C header files [PREFIX/include]
+  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
+  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
+  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
+  --infodir=DIR           info documentation [DATAROOTDIR/info]

+  --disable-dependency-tracking  speeds up one-time build
+  --enable-dependency-tracking   do not reject slow dependency extractors
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a

+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help

+              reported by James Lemley on 2005-10-05; see
+              http://lists.gnu.org/archive/html/bug-coreutils/2005-10/msg00086.html
+              This test is not quite right, since xlc is allowed to
+              reject this program, as the initializer for xlcbug is
+              not one of the forms that C requires support for.
+              However, doing the test right would require a run-time
+              test, and that would make cross-compilation harder.
+              Let us hope that IBM fixes the xlc bug, and also adds
+              support for this kind of constant expression.  In the
+              meantime, this test will reject xlc, which is OK, since
+              our stdbool.h substitute should suffice.  We also test
+              this with GCC, where it should work, to detect more
+              quickly whether someone messes up the test in the
+              future.  */

+>Chapter 1. Introduction</H1
+><P
+>The LW tool chain provides utilities for building binaries for MC6809 and
+HD6309 CPUs. The tool chain includes a cross-assembler and a cross-linker
+which support several styles of output.</P

+>1.1. History</A
+></H1
+><P
+>For a long time, I have had an interest in creating an operating system for
+the Coco3. I finally started working on that project around the beginning of
+2006. I had a number of assemblers I could choose from. Eventually, I settled
+on one and started tinkering. After a while, I realized that assembler was not
+going to be sufficient due to lack of macros and issues with forward references.
+Then I tried another which handled forward references correctly but still did
+not support macros. I looked around at other assemblers and they all lacked
+one feature or another that I really wanted for creating my operating system.</P
+><P
+>The solution seemed clear at that point. I am a fair programmer so I figured
+I could write an assembler that would do everything I wanted an assembler to
+do. Thus the LWASM probject was born. After more than two years of on and off
+work, version 1.0 of LWASM was released in October of 2008.</P
+><P
+>As the aforementioned operating system project progressed further, it became
+clear that while assembling the whole project through a single file was doable,
+it was not practical. When I found myself playing some fancy games with macros
+in a bid to simulate sections, I realized I needed a means of assembling
+source files separately and linking them later. This spawned a major development
+effort to add an object file support to LWASM. It also spawned the LWLINK
+project to provide a means to actually link the files.</P

+>Chapter 5. Libraries and LWAR</H1
+><P
+>LWTOOLS also includes a tool for managing libraries. These are analogous to
+the static libraries created with the "ar" tool on POSIX systems. Each library
+file contains one or more object files. The linker will treat the object
+files within a library as though they had been specified individually on
+the command line except when resolving external references. External references
+are looked up first within the object files within the library and then, if
+not found, the usual lookup based on the order the files are specified on
+the command line occurs.</P
+><P
+>The tool for creating these libary files is called LWAR.</P

+>Chapter 6. Object Files</H1
+><P
+>LWTOOLS uses a proprietary object file format. It is proprietary in the sense
+that it is specific to LWTOOLS, not that it is a hidden format. It would be
+hard to keep it hidden in an open source tool chain anyway. This chapter
+documents the object file format.</P
+><P
+>An object file consists of a series of sections each of which contains a
+list of exported symbols, a list of incomplete references, and a list of
+"local" symbols which may be used in calculating incomplete references. Each
+section will obviously also contain the object code.</P
+><P
+>Exported symbols must be completely resolved to an address within the
+section it is exported from. That is, an exported symbol must be a constant
+rather than defined in terms of other symbols.</P
+><P
+>Each object file starts with a magic number and version number. The magic
+number is the string "LWOBJ16" for this 16 bit object file format. The only
+defined version number is currently 0. Thus, the first 8 bytes of the object
+file are <FONT
+COLOR="RED"
+>4C574F424A313600</FONT
+></P
+><P
+>Each section has the following items in order:</P
+><P
+></P
+><UL
+><LI
+><P
+>section name</P
+></LI
+><LI
+><P
+>flags</P

+></LI
+><LI
+><P
+>list of exported symbols (and addresses within the section)</P
+></LI
+><LI
+><P
+>list of incomplete references along with the expressions to calculate them</P
+></LI
+><LI
+><P
+>the actual object code (for non-BSS sections)</P
+></LI
+></UL
+><P
+>The section starts with the name of the section with a NUL termination
+followed by a series of flag bytes terminated by NUL. There are only two
+flag bytes defined. A NUL (0) indicates no more flags and a value of 1
+indicates the section is a BSS section. For a BSS section, no actual
+code is included in the object file.</P
+><P
+>Either a NULL section name or end of file indicate the presence of no more
+sections.</P
+><P
+>Each entry in the exported and local symbols table consists of the symbol
+(NUL terminated) followed by two bytes which contain the value in big endian
+order. The end of a symbol table is indicated by a NULL symbol name.</P
+><P
+>Each entry in the incomplete references table consists of an expression
+followed by a 16 bit offset where the reference goes. Expressions are
+defined as a series of terms up to an "end of expression" term. Each term
+consists of a single byte which identifies the type of term (see below)
+followed by any data required by the term. Then end of the list is flagged
+by a NULL expression (only an end of expression term).</P

+>Chapter 1. Introduction</H1
+><P
+>The LW tool chain provides utilities for building binaries for MC6809 and
+HD6309 CPUs. The tool chain includes a cross-assembler and a cross-linker
+which support several styles of output.</P
+><DIV

+>1.1. History</A
+></H2
+><P
+>For a long time, I have had an interest in creating an operating system for
+the Coco3. I finally started working on that project around the beginning of
+2006. I had a number of assemblers I could choose from. Eventually, I settled
+on one and started tinkering. After a while, I realized that assembler was not
+going to be sufficient due to lack of macros and issues with forward references.
+Then I tried another which handled forward references correctly but still did
+not support macros. I looked around at other assemblers and they all lacked
+one feature or another that I really wanted for creating my operating system.</P
+><P
+>The solution seemed clear at that point. I am a fair programmer so I figured
+I could write an assembler that would do everything I wanted an assembler to
+do. Thus the LWASM probject was born. After more than two years of on and off
+work, version 1.0 of LWASM was released in October of 2008.</P
+><P
+>As the aforementioned operating system project progressed further, it became
+clear that while assembling the whole project through a single file was doable,
+it was not practical. When I found myself playing some fancy games with macros
+in a bid to simulate sections, I realized I needed a means of assembling
+source files separately and linking them later. This spawned a major development
+effort to add an object file support to LWASM. It also spawned the LWLINK
+project to provide a means to actually link the files.</P

+>Chapter 2. Output Formats</H1
+><P
+>The LW tool chain supports multiple output formats. Each format has its
+advantages and disadvantages. Each format is described below.</P
+><DIV
+CLASS="SECTION"
+><HR><H2
+CLASS="SECTION"
+><A
+NAME="AEN21"
+>2.1. Raw Binaries</A
+></H2
+><P
+>A raw binary is simply a string of bytes. There are no headers or other
+niceties. Both LWLINK and LWASM support generating raw binaries. ORG directives
+in the source code only serve to set the addresses that will be used for
+symbols but otherwise have no direct impact on the resulting binary.</P
+></DIV
+><DIV
+CLASS="SECTION"
+><HR><H2
+CLASS="SECTION"
+><A
+NAME="AEN24"
+>2.2. DECB Binaries</A
+></H2
+><P
+>A DECB binary is compatible with the LOADM command in Disk Extended
+Color Basic on the CoCo. They are also compatible with CLOADM from Extended
+Color Basic. These binaries include the load address of the binary as well
+as encoding an execution address. These binaries may contain multiple loadable
+sections, each of which has its own load address.</P
+><P
+>Each binary starts with a preamble. Each preamble is five bytes long. The
+first byte is zero. The next two bytes specify the number of bytes to load
+and the last two bytes specify the address to load the bytes at. Then, a
+string of bytes follows. After this string of bytes, there may be another
+preamble or a postamble. A postamble is also five bytes in length. The first
+byte of the postamble is $FF, the next two are zero, and the last two are
+the execution address for the binary.</P
+><P
+>Both LWASM and LWLINK can output this format.</P
+></DIV
+><DIV
+CLASS="SECTION"

+CLASS="SECTION"
+><A
+NAME="AEN29"
+>2.3. OS9 Modules</A
+></H2
+><P
+>&#13;Since version 2.5, LWASM is able to generate OS9 modules. The syntax is
+basically the same as for other assemblers.  A module starts with the MOD
+directive and ends with the EMOD directive.  The OS9 directive is provided
+as a shortcut for writing system calls.&#13;</P
+><P
+>&#13;LWASM does NOT provide an OS9Defs file. You must provide your own. Also note
+that the common practice of using "ifp1" around the inclusion of the OS9Defs
+file is discouraged as it is pointless and can lead to unintentional
+problems and phasing errors.  Because LWASM reads each file exactly once,
+there is no benefit to restricting the inclusion to the first assembly pass.&#13;</P
+><P
+>&#13;It is also critical to understand that unlike many OS9 assemblers, LWASM
+does NOT maintain a separate data address counter.  Thus, you must define
+all your data offsets and so on outside of the mod/emod segment.  It is,
+therefore, likely that source code targeted at other assemblers will require
+edits to build correctly.&#13;</P
+><P
+>&#13;LWLINK does not, yet, have the ability to create OS9 modules from object
+files.&#13;</P

+CLASS="SECTION"

+NAME="AEN35"
+>2.4. Object Files</A
+></H2
+><P
+>LWASM supports generating a proprietary object file format which is
+described in <A
+HREF="#OBJCHAP"
+>Chapter 6</A
+>. LWLINK is then used to link these
+object files into a final binary in any of LWLINK's supported binary
+formats.</P
+><P
+>Object files also support the concept of sections which are not valid
+for other output types. This allows related code from each object file
+linked to be collapsed together in the final binary.</P
+><P
+>Object files are very flexible in that they allow references that are not
+known at assembly time to be resolved at link time.  However, because the
+addresses of such references are not known at assembly time, there is no way
+for the assembler to deduce that an eight bit addressing mode is possible. 
+That means the assember will default to using sixteen bit addressing
+whenever an external or cross-section reference is used.</P
+><P
+>As of LWASM 2.4, it is possible to force direct page addressing for an
+external reference.  Care must be taken to ensure the resulting addresses
+are really in the direct page since the linker does not know what the direct
+page is supposed to be and does not emit errors for byte overflows.</P
+><P
+>It is also possible to use external references in an eight bit immediate
+mode instruction.  In this case, only the low order eight bits will be used. 
+Again, no byte overflows will be flagged.</P

+>LWASM supports all documented MC6809 instructions as defined by Motorola. 
+It also supports all known HD6309 instructions.  While there is general
+agreement on the pneumonics for most of the 6309 instructions, there is some
+variance with the block transfer instructions. TFM for all four variations
+seems to have gained the most traction and, thus, this is the form that is
+recommended for LWASM. However, it also supports COPY, COPY-, IMP, EXP,
+TFRP, TFRM, TFRS, and TFRR. It further adds COPY+ as a synomym for COPY,
+IMPLODE for IMP, and EXPAND for EXP.</P
+><P
+>By default, LWASM accepts 6309 instructions. However, using the
+<CODE
+CLASS="PARAMETER"
+>--6809</CODE
+> parameter, you can cause it to throw errors on
+6309 instructions instead.</P
+><P
+>The standard addressing mode specifiers are supported. These are the
+hash sign ("#") for immediate mode, the less than sign ("&lt;") for forced
+eight bit modes, and the greater than sign ("&gt;") for forced sixteen bit modes.</P
+><P
+>Additionally, LWASM supports using the asterisk ("*") to indicate

+>Each line may start with a symbol. If a symbol is present, there must not

+If applicable, the operand follows separated by whitespace. Following the

+><P
+> It is important to note that operands cannot contain any whitespace
+except in the case of delimited strings.  This is because the first
+whitespace character will be interpreted as the separator between the
+operand column and the comment.  This behaviour is required for approximate
+source compatibility with other 6x09 assemblers.  </P
+><P
+>A comment can also be introduced with a * or a ;. The comment character is

+will also ignore lines that begin with a #. This should not be used as a general
+comment character, however.</P
+><P

+the operand fields. Symbols, however, are case sensitive.</P
+><P
+> As of version 2.6, LWASM supports files with line numbers.  If line
+numbers are present, the line must start with a digit.  The line number
+itself must consist only of digits.  The line number must then be followed

+be considered a local scope barrier. Macros each have their own local symbol
+scope as well (which has a side effect that you cannot use a local symbol

+>&#13;Numbers can be expressed in binary, octal, decimal, or hexadecimal. Binary
+numbers may be prefixed with a "%" symbol or suffixed with a "b" or "B".
+Octal numbers may be prefixed with "@" or suffixed with "Q", "q", "O", or
+"o". Hexadecimal numbers may be prefixed with "$", "0x" or "0X", or suffixed
+with "H". No prefix or suffix is required for decimal numbers but they can
+be prefixed with "&amp;" if desired. Any constant which begins with a letter
+must be expressed with the correct prefix base identifier or be prefixed
+with a 0. Thus hexadecimal FF would have to be written either 0FFH or $FF.
+Numbers are not case sensitive.&#13;</P
+><P
+> A symbol may appear at any point where a number is acceptable. The
+special symbol "*" can be used to represent the starting address of the
+current source line within expressions. </P
+><P
+>The ASCII value of a character can be included by prefixing it with a
+single quote ('). The ASCII values of two characters can be included by
+prefixing the characters with a quote (").</P
+><P
+>&#13;LWASM supports the following basic binary operators: +, -, *, /, and %. 
+These represent addition, subtraction, multiplication, division, and
+modulus.  It also supports unary negation and unary 1's complement (- and ^
+respectively).  It is also possible to use ~ for the unary 1's complement
+operator.  For completeness, a unary positive (+) is supported though it is
+a no-op.  LWASM also supports using |, &#38;, and ^ for bitwise or, bitwise and,
+and bitwise exclusive or respectively.&#13;</P
+><P
+>&#13;Operator precedence follows the usual rules. Multiplication, division, and
+modulus take precedence over addition and subtraction.  Unary operators take
+precedence over binary operators.  Bitwise operators are lower precdence
+than addition and subtraction.  To force a specific order of evaluation,
+parentheses can be used in the usual manner.&#13;</P
+><P
+>&#13;As of LWASM 2.5, the operators &#38;&#38; and || are recognized for boolean and and
+boolean or respectively.  They will return either 0 or 1 (false or true). 
+They have the lowest precedence of all the binary operators.&#13;</P

+>3.7. Macros</A
+></H2
+><P
+>LWASM is a macro assembler. A macro is simply a name that stands in for a
+series of instructions. Once a macro is defined, it is used like any other
+assembler directive. Defining a macro can be considered equivalent to adding
+additional assembler directives.</P
+><P
+>Macros may accept parameters. These parameters are referenced within
+a macro by the a backslash ("\") followed by a digit 1 through 9 for the first
+through ninth parameters. They may also be referenced by enclosing the
+decimal parameter number in braces ("{num}"). These parameter references
+are replaced with the verbatim text of the parameter passed to the macro. A
+reference to a non-existent parameter will be replaced by an empty string.
+Macro parameters are expanded everywhere on each source line. That means
+the parameter to a macro could be used as a symbol or it could even appear
+in a comment or could cause an entire source line to be commented out
+when the macro is expanded.</P
+><P
+>Parameters passed to a macro are separated by commas and the parameter list
+is terminated by any whitespace. This means that neither a comma nor whitespace
+may be included in a macro parameter.</P
+><P
+>Macro expansion is done recursively. That is, within a macro, macros are
+expanded. This can lead to infinite loops in macro expansion. If the assembler
+hangs for a long time while assembling a file that uses macros, this may be
+the reason.</P
+><P
+>Each macro expansion receives its own local symbol context which is not
+inherited by any macros called by it nor is it inherited from the context
+the macro was instantiated in. That means it is possible to use local symbols
+within macros without having them collide with symbols in other macros or
+outside the macro itself. However, this also means that using a local symbol
+as a parameter to a macro, while legal, will not do what it would seem to do
+as it will result in looking up the local symbol in the macro's symbol context
+rather than the enclosing context where it came from, likely yielding either
+an undefined symbol error or bizarre assembly results.</P
+><P
+>Note that there is no way to define a macro as local to a symbol context. All
+macros are part of the global macro namespace. However, macros have a separate
+namespace from symbols so it is possible to have a symbol with the same name
+as a macro.</P
+><P
+>Macros are defined only during the first pass. Macro expansion also
+only occurs during the first pass. On the second pass, the macro
+definition is simply ignored. Macros must be defined before they are used.</P

+>3.9. Object Files and Sections</A
+></H2
+><P
+>The object file target is very useful for large project because it allows
+multiple files to be assembled independently and then linked into the final
+binary at a later time. It allows only the small portion of the project
+that was modified to be re-assembled rather than requiring the entire set
+of source code to be available to the assembler in a single assembly process.
+This can be particularly important if there are a large number of macros,
+symbol definitions, or other metadata that uses resources at assembly time.
+By far the largest benefit, however, is keeping the source files small enough
+for a mere mortal to find things in them.</P
+><P
+>With multi-file projects, there needs to be a means of resolving references to
+symbols in other source files. These are known as external references. The
+addresses of these symbols cannot be known until the linker joins all the
+object files into a single binary. This means that the assembler must be
+able to output the object code without knowing the value of the symbol. This
+places some restrictions on the code generated by the assembler. For
+example, the assembler cannot generate direct page addressing for instructions
+that reference external symbols because the address of the symbol may not
+be in the direct page. Similarly, relative branches and PC relative addressing
+cannot be used in their eight bit forms. Everything that must be resolved
+by the linker must be assembled to use the largest address size possible to
+allow the linker to fill in the correct value at link time. Note that the
+same problem applies to absolute address references as well, even those in
+the same source file, because the address is not known until link time.</P
+><P
+>It is often desired in multi-file projects to have code of various types grouped
+together in the final binary generated by the linker as well. The same applies
+to data. In order for the linker to do that, the bits that are to be grouped
+must be tagged in some manner. This is where the concept of sections comes in.
+Each chunk of code or data is part of a section in the object file. Then,
+when the linker reads all the object files, it coalesces all sections of the
+same name into a single section and then considers it as a unit.</P
+><P
+>The existence of sections, however, raises a problem for symbols even
+within the same source file. Thus, the assembler must treat symbols from
+different sections within the same source file in the same manner as external
+symbols. That is, it must leave them for the linker to resolve at link time,
+with all the limitations that entails.</P
+><P
+>In the object file target mode, LWASM requires all source lines that
+cause bytes to be output to be inside a section. Any directives that do
+not cause any bytes to be output can appear outside of a section. This includes
+such things as EQU or RMB. Even ORG can appear outside a section. ORG, however,
+makes no sense within a section because it is the linker that determines
+the starting address of the section's code, not the assembler.</P
+><P
+>All symbols defined globally in the assembly process are local to the 
+source file and cannot be exported. All symbols defined within a section are
+considered local to the source file unless otherwise explicitly exported.
+Symbols referenced from external source files must be declared external,
+either explicitly or by asking the assembler to assume that all undefined
+symbols are external.</P
+><P
+>It is often handy to define a number of memory addresses that will be
+used for data at run-time but which need not be included in the binary file.
+These memory addresses are not initialized until run-time, either by the
+program itself or by the program loader, depending on the operating environment.
+Such sections are often known as BSS sections. LWASM supports generating
+sections with a BSS attribute set which causes the section definition including
+symbols exported from that section and those symbols required to resolve
+references from the local file, but with no actual code in the object file.
+It is illegal for any source lines within a BSS flagged section to cause any
+bytes to be output.</P

+>Chapter 6. Object Files</H1
+><P
+>LWTOOLS uses a proprietary object file format. It is proprietary in the sense
+that it is specific to LWTOOLS, not that it is a hidden format. It would be
+hard to keep it hidden in an open source tool chain anyway. This chapter
+documents the object file format.</P
+><P
+>An object file consists of a series of sections each of which contains a
+list of exported symbols, a list of incomplete references, and a list of
+"local" symbols which may be used in calculating incomplete references. Each
+section will obviously also contain the object code.</P
+><P
+>Exported symbols must be completely resolved to an address within the
+section it is exported from. That is, an exported symbol must be a constant
+rather than defined in terms of other symbols.</P
+><P
+>Each object file starts with a magic number and version number. The magic
+number is the string "LWOBJ16" for this 16 bit object file format. The only
+defined version number is currently 0. Thus, the first 8 bytes of the object
+file are <FONT
+COLOR="RED"
+>4C574F424A313600</FONT
+></P
+><P
+>Each section has the following items in order:</P
+><P
+></P
+><UL
+><LI
+><P
+>section name</P

+><LI

+>flags</P

+><P
+>list of incomplete references along with the expressions to calculate them</P
+></LI
+><LI
+><P
+>the actual object code (for non-BSS sections)</P
+></LI
+></UL
+><P
+>The section starts with the name of the section with a NUL termination
+followed by a series of flag bytes terminated by NUL. There are only two
+flag bytes defined. A NUL (0) indicates no more flags and a value of 1
+indicates the section is a BSS section. For a BSS section, no actual
+code is included in the object file.</P
+><P
+>Either a NULL section name or end of file indicate the presence of no more
+sections.</P
+><P
+>Each entry in the exported and local symbols table consists of the symbol
+(NUL terminated) followed by two bytes which contain the value in big endian
+order. The end of a symbol table is indicated by a NULL symbol name.</P
+><P
+>Each entry in the incomplete references table consists of an expression
+followed by a 16 bit offset where the reference goes. Expressions are
+defined as a series of terms up to an "end of expression" term. Each term
+consists of a single byte which identifies the type of term (see below)
+followed by any data required by the term. Then end of the list is flagged
+by a NULL expression (only an end of expression term).</P

+>LWASM supports all documented MC6809 instructions as defined by Motorola. 
+It also supports all known HD6309 instructions.  While there is general
+agreement on the pneumonics for most of the 6309 instructions, there is some
+variance with the block transfer instructions. TFM for all four variations
+seems to have gained the most traction and, thus, this is the form that is
+recommended for LWASM. However, it also supports COPY, COPY-, IMP, EXP,
+TFRP, TFRM, TFRS, and TFRR. It further adds COPY+ as a synomym for COPY,
+IMPLODE for IMP, and EXPAND for EXP.</P
+><P
+>By default, LWASM accepts 6309 instructions. However, using the
+<CODE
+CLASS="PARAMETER"
+>--6809</CODE
+> parameter, you can cause it to throw errors on
+6309 instructions instead.</P
+><P
+>The standard addressing mode specifiers are supported. These are the
+hash sign ("#") for immediate mode, the less than sign ("&lt;") for forced
+eight bit modes, and the greater than sign ("&gt;") for forced sixteen bit modes.</P
+><P
+>Additionally, LWASM supports using the asterisk ("*") to indicate
+base page addressing. This should not be used in hand-written source code,
+however, because it is non-standard and may or may not be present in future
+versions of LWASM.</P

+>LWASM accepts plain text files in a relatively free form. It can handle
+lines terminated with CR, LF, CRLF, or LFCR which means it should be able
+to assemble files on any platform on which it compiles.</P
+><P
+>Each line may start with a symbol. If a symbol is present, there must not
+be any whitespace preceding it. It is legal for a line to contain nothing
+but a symbol.</P
+><P
+>The op code is separated from the symbol by whitespace. If there is
+no symbol, there must be at least one white space character preceding it.
+If applicable, the operand follows separated by whitespace. Following the
+opcode and operand is an optional comment.</P
+><P
+> It is important to note that operands cannot contain any whitespace
+except in the case of delimited strings.  This is because the first
+whitespace character will be interpreted as the separator between the
+operand column and the comment.  This behaviour is required for approximate
+source compatibility with other 6x09 assemblers.  </P
+><P
+>A comment can also be introduced with a * or a ;. The comment character is
+optional for end of statement comments. However, if a symbol is the only
+thing present on the line other than the comment, the comment character is
+mandatory to prevent the assembler from interpreting the comment as an opcode.</P
+><P
+>For compatibility with the output generated by some C preprocessors, LWASM
+will also ignore lines that begin with a #. This should not be used as a general
+comment character, however.</P
+><P
+>The opcode is not treated case sensitively. Neither are register names in
+the operand fields. Symbols, however, are case sensitive.</P
+><P
+> As of version 2.6, LWASM supports files with line numbers.  If line
+numbers are present, the line must start with a digit.  The line number
+itself must consist only of digits.  The line number must then be followed
+by either the end of the line or exactly one white space character.  After
+that white space character, the lines are interpreted exactly as above. </P

+which contains either a "?" or a "@", which can appear anywhere in the symbol.
+The scope of a local symbol is determined by a number of factors. First,
+each included file gets its own local symbol scope. A blank line will also
+be considered a local scope barrier. Macros each have their own local symbol
+scope as well (which has a side effect that you cannot use a local symbol
+as an argument to a macro). There are other factors as well. In general,
+a local symbol is restricted to the block of code it is defined within.</P
+><P
+>By default, unless assembling to the os9 target, a "$" in the symbol will
+also make it local.  This can be controlled by the "dollarlocal" and
+"nodollarlocal" pragmas.  In the absence of a pragma to the contrary, for
+the os9 target, a "$" in the symbol will not make it considered local while
+for all other targets it will.</P

+><P
+>&#13;Numbers can be expressed in binary, octal, decimal, or hexadecimal. Binary
+numbers may be prefixed with a "%" symbol or suffixed with a "b" or "B".
+Octal numbers may be prefixed with "@" or suffixed with "Q", "q", "O", or
+"o". Hexadecimal numbers may be prefixed with "$", "0x" or "0X", or suffixed
+with "H". No prefix or suffix is required for decimal numbers but they can
+be prefixed with "&amp;" if desired. Any constant which begins with a letter
+must be expressed with the correct prefix base identifier or be prefixed
+with a 0. Thus hexadecimal FF would have to be written either 0FFH or $FF.
+Numbers are not case sensitive.&#13;</P
+><P
+> A symbol may appear at any point where a number is acceptable. The
+special symbol "*" can be used to represent the starting address of the
+current source line within expressions. </P
+><P
+>The ASCII value of a character can be included by prefixing it with a
+single quote ('). The ASCII values of two characters can be included by
+prefixing the characters with a quote (").</P
+><P
+>&#13;LWASM supports the following basic binary operators: +, -, *, /, and %. 
+These represent addition, subtraction, multiplication, division, and
+modulus.  It also supports unary negation and unary 1's complement (- and ^
+respectively).  It is also possible to use ~ for the unary 1's complement
+operator.  For completeness, a unary positive (+) is supported though it is
+a no-op.  LWASM also supports using |, &#38;, and ^ for bitwise or, bitwise and,
+and bitwise exclusive or respectively.&#13;</P
+><P
+>&#13;Operator precedence follows the usual rules. Multiplication, division, and
+modulus take precedence over addition and subtraction.  Unary operators take
+precedence over binary operators.  Bitwise operators are lower precdence
+than addition and subtraction.  To force a specific order of evaluation,
+parentheses can be used in the usual manner.&#13;</P
+><P
+>&#13;As of LWASM 2.5, the operators &#38;&#38; and || are recognized for boolean and and
+boolean or respectively.  They will return either 0 or 1 (false or true). 
+They have the lowest precedence of all the binary operators.&#13;</P

+><P
+>&#13;Since version 2.5, LWASM is able to generate OS9 modules. The syntax is
+basically the same as for other assemblers.  A module starts with the MOD
+directive and ends with the EMOD directive.  The OS9 directive is provided
+as a shortcut for writing system calls.&#13;</P
+><P
+>&#13;LWASM does NOT provide an OS9Defs file. You must provide your own. Also note
+that the common practice of using "ifp1" around the inclusion of the OS9Defs
+file is discouraged as it is pointless and can lead to unintentional
+problems and phasing errors.  Because LWASM reads each file exactly once,
+there is no benefit to restricting the inclusion to the first assembly pass.&#13;</P
+><P
+>&#13;It is also critical to understand that unlike many OS9 assemblers, LWASM
+does NOT maintain a separate data address counter.  Thus, you must define
+all your data offsets and so on outside of the mod/emod segment.  It is,
+therefore, likely that source code targeted at other assemblers will require
+edits to build correctly.&#13;</P

+files.&#13;</P

+><P
+>LWASM supports generating a proprietary object file format which is
+described in <A
+HREF="c835.html"
+>Chapter 6</A
+>. LWLINK is then used to link these
+object files into a final binary in any of LWLINK's supported binary
+formats.</P
+><P
+>Object files also support the concept of sections which are not valid
+for other output types. This allows related code from each object file
+linked to be collapsed together in the final binary.</P
+><P
+>Object files are very flexible in that they allow references that are not
+known at assembly time to be resolved at link time.  However, because the
+addresses of such references are not known at assembly time, there is no way
+for the assembler to deduce that an eight bit addressing mode is possible. 
+That means the assember will default to using sixteen bit addressing
+whenever an external or cross-section reference is used.</P
+><P
+>As of LWASM 2.4, it is possible to force direct page addressing for an
+external reference.  Care must be taken to ensure the resulting addresses
+are really in the direct page since the linker does not know what the direct
+page is supposed to be and does not emit errors for byte overflows.</P
+><P
+>It is also possible to use external references in an eight bit immediate
+mode instruction.  In this case, only the low order eight bits will be used. 
+Again, no byte overflows will be flagged.</P

+>3.7. Macros</A
+></H1
+><P
+>LWASM is a macro assembler. A macro is simply a name that stands in for a
+series of instructions. Once a macro is defined, it is used like any other
+assembler directive. Defining a macro can be considered equivalent to adding
+additional assembler directives.</P
+><P
+>Macros may accept parameters. These parameters are referenced within
+a macro by the a backslash ("\") followed by a digit 1 through 9 for the first
+through ninth parameters. They may also be referenced by enclosing the
+decimal parameter number in braces ("{num}"). These parameter references
+are replaced with the verbatim text of the parameter passed to the macro. A
+reference to a non-existent parameter will be replaced by an empty string.
+Macro parameters are expanded everywhere on each source line. That means
+the parameter to a macro could be used as a symbol or it could even appear
+in a comment or could cause an entire source line to be commented out
+when the macro is expanded.</P
+><P
+>Parameters passed to a macro are separated by commas and the parameter list
+is terminated by any whitespace. This means that neither a comma nor whitespace
+may be included in a macro parameter.</P
+><P
+>Macro expansion is done recursively. That is, within a macro, macros are
+expanded. This can lead to infinite loops in macro expansion. If the assembler
+hangs for a long time while assembling a file that uses macros, this may be
+the reason.</P
+><P
+>Each macro expansion receives its own local symbol context which is not
+inherited by any macros called by it nor is it inherited from the context
+the macro was instantiated in. That means it is possible to use local symbols
+within macros without having them collide with symbols in other macros or
+outside the macro itself. However, this also means that using a local symbol
+as a parameter to a macro, while legal, will not do what it would seem to do
+as it will result in looking up the local symbol in the macro's symbol context
+rather than the enclosing context where it came from, likely yielding either
+an undefined symbol error or bizarre assembly results.</P
+><P
+>Note that there is no way to define a macro as local to a symbol context. All
+macros are part of the global macro namespace. However, macros have a separate
+namespace from symbols so it is possible to have a symbol with the same name
+as a macro.</P
+><P
+>Macros are defined only during the first pass. Macro expansion also
+only occurs during the first pass. On the second pass, the macro
+definition is simply ignored. Macros must be defined before they are used.</P
+><P
+>The following directives are used when defining macros.</P
+><P
+></P
+><DIV
+CLASS="VARIABLELIST"
+><DL
+><DT
+><CODE
+CLASS="PARAMETER"

+>macroname</CODE

+be relied upon.</P

+assembler does the same thing using the name of the variable.  You will see
+these symbols in the symbol table when the assembler is instructed to
+provide a listing.  For instance, the above listing will create the

+tstruct2.f2 (1), sizeof{tstruct2} (2), tstruct.field1 (0), tstruct.field2

+>3.9. Object Files and Sections</A
+></H1
+><P
+>The object file target is very useful for large project because it allows
+multiple files to be assembled independently and then linked into the final
+binary at a later time. It allows only the small portion of the project
+that was modified to be re-assembled rather than requiring the entire set
+of source code to be available to the assembler in a single assembly process.
+This can be particularly important if there are a large number of macros,
+symbol definitions, or other metadata that uses resources at assembly time.
+By far the largest benefit, however, is keeping the source files small enough
+for a mere mortal to find things in them.</P
+><P
+>With multi-file projects, there needs to be a means of resolving references to
+symbols in other source files. These are known as external references. The
+addresses of these symbols cannot be known until the linker joins all the
+object files into a single binary. This means that the assembler must be
+able to output the object code without knowing the value of the symbol. This
+places some restrictions on the code generated by the assembler. For
+example, the assembler cannot generate direct page addressing for instructions
+that reference external symbols because the address of the symbol may not
+be in the direct page. Similarly, relative branches and PC relative addressing
+cannot be used in their eight bit forms. Everything that must be resolved
+by the linker must be assembled to use the largest address size possible to
+allow the linker to fill in the correct value at link time. Note that the
+same problem applies to absolute address references as well, even those in
+the same source file, because the address is not known until link time.</P
+><P
+>It is often desired in multi-file projects to have code of various types grouped
+together in the final binary generated by the linker as well. The same applies
+to data. In order for the linker to do that, the bits that are to be grouped
+must be tagged in some manner. This is where the concept of sections comes in.
+Each chunk of code or data is part of a section in the object file. Then,
+when the linker reads all the object files, it coalesces all sections of the
+same name into a single section and then considers it as a unit.</P
+><P
+>The existence of sections, however, raises a problem for symbols even
+within the same source file. Thus, the assembler must treat symbols from
+different sections within the same source file in the same manner as external
+symbols. That is, it must leave them for the linker to resolve at link time,
+with all the limitations that entails.</P
+><P
+>In the object file target mode, LWASM requires all source lines that
+cause bytes to be output to be inside a section. Any directives that do
+not cause any bytes to be output can appear outside of a section. This includes
+such things as EQU or RMB. Even ORG can appear outside a section. ORG, however,
+makes no sense within a section because it is the linker that determines
+the starting address of the section's code, not the assembler.</P
+><P
+>All symbols defined globally in the assembly process are local to the 
+source file and cannot be exported. All symbols defined within a section are
+considered local to the source file unless otherwise explicitly exported.
+Symbols referenced from external source files must be declared external,
+either explicitly or by asking the assembler to assume that all undefined
+symbols are external.</P
+><P
+>It is often handy to define a number of memory addresses that will be
+used for data at run-time but which need not be included in the binary file.
+These memory addresses are not initialized until run-time, either by the
+program itself or by the program loader, depending on the operating environment.
+Such sections are often known as BSS sections. LWASM supports generating
+sections with a BSS attribute set which causes the section definition including
+symbols exported from that section and those symbols required to resolve
+references from the local file, but with no actual code in the object file.
+It is illegal for any source lines within a BSS flagged section to cause any
+bytes to be output.</P
+><P
+>The following directives apply to section handling.</P
+><P
+></P

+considered part of the section <CODE

+may appear multiple times in which case it is as though all the code from
+all the instances of that section appeared adjacent within the source file.
+However, <CODE
+CLASS="PARAMETER"
+>flags</CODE
+> may only be specified on the first
+instance of the section.</P
+><P
+>There is a single flag supported in <CODE
+CLASS="PARAMETER"
+>flags</CODE
+>. The
+flag <CODE
+CLASS="PARAMETER"
+>bss</CODE
+> will cause the section to be treated as a BSS
+section and, thus, no code will be included in the object file nor will any
+bytes be permitted to be output.</P
+><P
+>If the section name is "bss" or ".bss" in any combination of upper and
+lower case, the section is assumed to be a BSS section. In that case,
+the flag <CODE
+CLASS="PARAMETER"
+>!bss</CODE
+> can be used to override this assumption.</P
+><P
+>If assembly is already happening within a section, the section is implicitly
+ended and the new section started. This is not considered an error although
+it is recommended that all sections be explicitly closed.</P
+></DD
+><DT

+><DD
+><P
+>This directive ends the current section. This puts assembly outside of any
+sections until the next SECTION directive. ENDSECTION is the preferred form.

+>There are a number of options that affect the way assembly is performed.

+not portable between assemblers.</P
+><P
+>LWASM supports a number of pragmas that affect code generation or

+for correct functioning of the code.</P
+></DD
+></DL
+></DIV
+><P
+>Each pragma supported has a positive version and a negative version.
+The positive version enables the pragma while the negative version disables
+it. The negatitve version is simply the positive version with "no" prefixed

+>When in force, this pragma enables an optimization affecting indexed addressing
+modes. When the offset expression in an indexed mode evaluates to zero but is
+not explicity written as 0, this will replace the operand with the equivalent
+no offset mode, thus creating slightly faster code. Because of the advantages
+of this optimization, it is enabled by default.</P
+></DD
+><DT
+>cescapes</DT
+><DD
+><P
+>This pragma will cause strings in the FCC, FCS, and FCN pseudo operations to
+have C-style escape sequences interpreted. The one departure from the official
+spec is that unrecognized escape sequences will return either the character
+immediately following the backslash or some undefined value. Do not rely
+on the behaviour of undefined escape sequences.</P
+></DD
+><DT
+>importundefexport</DT
+><DD
+><P
+>This pragma is only valid for targets that support external references. When
+in force, it will cause the EXPORT directive to act as IMPORT if the symbol
+to be exported is not defined.  This is provided for compatibility with the
+output of gcc6809 and should not be used in hand written code.  Because of
+the confusion this pragma can cause, it is disabled by default.</P
+></DD
+><DT
+>undefextern</DT
+><DD
+><P
+>This pragma is only valid for targets that support external references. When in
+force, if the assembler sees an undefined symbol on the second pass, it will
+automatically define it as an external symbol. This automatic definition will
+apply for the remainder of the assembly process, even if the pragma is
+subsequently turned off. Because this behaviour would be potentially surprising,
+this pragma defaults to off.</P
+><P
+>The primary use for this pragma is for projects that share a large number of
+symbols between source files. In such cases, it is impractical to enumerate
+all the external references in every source file. This allows the assembler
+and linker to do the heavy lifting while not preventing a particular source
+module from defining a local symbol of the same name as an external symbol
+if it does not need the external symbol. (This pragma will not cause an
+automatic external definition if there is already a locally defined symbol.)</P
+><P
+>This pragma will often be specified on the command line for large projects.
+However, depending on the specific dynamics of the project, it may be sufficient
+for one or two files to use this pragma internally.</P
+></DD
+><DT
+>dollarlocal</DT
+><DD
+><P
+>When set, a "$" in a symbol makes it local. When not set, "$" does not
+cause a symbol to be local.  It is set by default except when using the OS9
+target.</P

+>dollarnotlocal</DT
+><DD
+><P
+> This is the same as the "dollarlocal" pragma except its sense is

+>A linker script is used to instruct the linker about how to assemble the
+various sections into a completed binary. It consists of a series of
+directives which are considered in the order they are encountered.</P
+><P
+>The sections will appear in the resulting binary in the order they are
+specified in the script file. If a referenced section is not found, the linker will behave as though the
+section did exist but had a zero size, no relocations, and no exports.
+A section should only be referenced once. Any subsequent references will have
+an undefined effect.</P
+><P
+>All numbers are in linking scripts are specified in hexadecimal. All directives
+are case sensitive although the hexadecimal numbers are not.</P
+><P
+>A section name can be specified as a "*", then any section not
+already matched by the script will be matched. The "*" can be followed
+by a comma and a flag to narrow the section down slightly, also.
+If the flag is "!bss", then any section that is not flagged as a bss section
+will be matched. If the flag is "bss", then any section that is flagged as
+bss will be matched.</P
+><P
+>The following directives are understood in a linker script.</P
+><P

+CLASS="PARAMETER"

+>&#13;This causes the section <CODE

+> to load at
+<CODE
+CLASS="PARAMETER"
+>addr</CODE
+>. For the raw target, only one "load at" entry is
+allowed for non-bss sections and it must be the first one. For raw targets,
+it affects the addresses the linker assigns to symbols but has no other
+affect on the output. bss sections may all have separate load addresses but
+since they will not appear in the binary anyway, this is okay.</P
+><P
+>For the decb target, each "load" entry will cause a new "block" to be
+output to the binary which will contain the load address. It is legal for
+sections to overlap in this manner - the linker assumes the loader will sort
+everything out.</P
+></DD

+><DD
+><P
+>This will cause the execution address (entry point) to be the address
+specified (in hex) or the specified symbol name. The symbol name must
+match a symbol that is exported by one of the object files being linked.
+This has no effect for targets that do not encode the entry point into the
+resulting file. If not specified, the entry point is assumed to be address 0
+which is probably not what you want. The default link scripts for targets
+that support this directive automatically starts at the beginning of the
+first section (usually "init" or "code") that is emitted in the binary.</P

+/* alloca.c -- allocate automatically reclaimed memory
+   (Mostly) portable public-domain implementation -- D A Gwyn
+
+   This implementation of the PWB library alloca function,
+   which is used to allocate space off the run-time stack so
+   that it is automatically reclaimed upon procedure exit,
+   was inspired by discussions with J. Q. Johnson of Cornell.
+   J.Otto Tennant <jot@cray.com> contributed the Cray support.
+
+   There are some preprocessor constants that can
+   be defined when compiling for your specific system, for
+   improved efficiency; however, the defaults should be okay.
+
+   The general concept of this implementation is to keep
+   track of all alloca-allocated blocks, and reclaim any
+   that are found to be deeper in the stack than the current
+   invocation.  This heuristic does not reclaim storage as
+   soon as it becomes invalid, but it will do so eventually.
+
+   As a special case, alloca(0) reclaims storage without
+   allocating any.  It is a good idea to use alloca(0) in
+   your main control loop, etc. to force garbage collection.  */

+/* Scan elements of ARGV (whose length is ARGC) for option characters
+   given in OPTSTRING.
+
+   If an element of ARGV starts with '-', and is not exactly "-" or "--",
+   then it is an option element.  The characters of this element
+   (aside from the initial '-') are option characters.  If `getopt'
+   is called repeatedly, it returns successively each of the option characters
+   from each of the option elements.
+
+   If `getopt' finds another option character, it returns that character,
+   updating `optind' and `nextchar' so that the next call to `getopt' can
+   resume the scan with the following option character or ARGV-element.
+
+   If there are no more option characters, `getopt' returns -1.
+   Then `optind' is the index in ARGV of the first ARGV-element
+   that is not an option.  (The ARGV-elements have been permuted
+   so that those that are not options now come last.)
+
+   OPTSTRING is a string containing the legitimate option characters.
+   If an option character is seen that is not listed in OPTSTRING,
+   return '?' after printing an error message.  If you set `opterr' to
+   zero, the error message is suppressed but we still return '?'.
+
+   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+   so the following text in the same ARGV-element, or the text of the following
+   ARGV-element, is returned in `optarg'.  Two colons mean an option that
+   wants an optional arg; if there is text in the current ARGV-element,
+   it is returned in `optarg', otherwise `optarg' is set to zero.
+
+   If OPTSTRING starts with `-' or `+', it requests different methods of
+   handling the non-option ARGV-elements.
+   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+   Long-named options begin with `--' instead of `-'.
+   Their names may be abbreviated as long as the abbreviation is unique
+   or is an exact match for some defined option.  If they have an
+   argument, it follows the option name in the same ARGV-element, separated
+   from the option name by a `=', or else the in next ARGV-element.
+   When `getopt' finds a long-named option, it returns 0 if that option's
+   `flag' field is nonzero, the value of the option's `val' field
+   if the `flag' field is zero.
+
+   The elements of ARGV aren't really const, because we permute them.
+   But we pretend they're const in the prototype to be compatible
+   with other systems.
+
+   LONGOPTS is a vector of `struct option' terminated by an
+   element containing a name which is zero.
+
+   LONGIND returns the index in LONGOPT of the long-named option found.
+   It is only valid when a long-named option has been found by the most
+   recent call.
+
+   If LONG_ONLY is nonzero, '-' as well as '--' can introduce

+     with repeated_c.  This reduces the task to testing whether *any of the
+     four* bytes in longword1 is zero.
+
+     We compute tmp =
+       ((longword1 - repeated_one) & ~longword1) & (repeated_one << 7).
+     That is, we perform the following operations:
+       1. Subtract repeated_one.
+       2. & ~longword1.
+       3. & a mask consisting of 0x80 in every byte.
+     Consider what happens in each byte:
+       - If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
+         and step 3 transforms it into 0x80.  A carry can also be propagated
+         to more significant bytes.
+       - If a byte of longword1 is nonzero, let its lowest 1 bit be at
+         position k (0 <= k <= 7); so the lowest k bits are 0.  After step 1,
+         the byte ends in a single bit of value 0 and k bits of value 1.
+         After step 2, the result is just k bits of value 1: 2^k - 1.  After
+         step 3, the result is 0.  And no carry is produced.
+     So, if longword1 has only non-zero bytes, tmp is zero.
+     Whereas if longword1 has a zero byte, call j the position of the least
+     significant zero byte.  Then the result has a zero at positions 0, ...,
+     j-1 and a 0x80 at position j.  We cannot predict the result at the more
+     significant bytes (positions j+1..3), but it does not matter since we
+     already have a non-zero bit at position 8*j+7.
+
+     So, the test whether any byte in longword1 is zero is equivalent to
+     testing whether tmp is nonzero.  */

+     the four* bytes in the longword in question are equal to NUL or
+     c.  We first use an xor with repeated_c.  This reduces the task
+     to testing whether *any of the four* bytes in longword1 is zero.
+
+     We compute tmp =
+       ((longword1 - repeated_one) & ~longword1) & (repeated_one << 7).
+     That is, we perform the following operations:
+       1. Subtract repeated_one.
+       2. & ~longword1.
+       3. & a mask consisting of 0x80 in every byte.
+     Consider what happens in each byte:
+       - If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
+         and step 3 transforms it into 0x80.  A carry can also be propagated
+         to more significant bytes.
+       - If a byte of longword1 is nonzero, let its lowest 1 bit be at
+         position k (0 <= k <= 7); so the lowest k bits are 0.  After step 1,
+         the byte ends in a single bit of value 0 and k bits of value 1.
+         After step 2, the result is just k bits of value 1: 2^k - 1.  After
+         step 3, the result is 0.  And no carry is produced.
+     So, if longword1 has only non-zero bytes, tmp is zero.
+     Whereas if longword1 has a zero byte, call j the position of the least
+     significant zero byte.  Then the result has a zero at positions 0, ...,
+     j-1 and a 0x80 at position j.  We cannot predict the result at the more
+     significant bytes (positions j+1..3), but it does not matter since we
+     already have a non-zero bit at position 8*j+7.
+
+     The test whether any byte in longword1 is zero is equivalent
+     to testing whether tmp is nonzero.
+
+     This test can read beyond the end of a string, depending on where
+     C_IN is encountered.  However, this is considered safe since the
+     initialization phase ensured that the read will be aligned,
+     therefore, the read will not cross page boundaries and will not
+     cause a fault.  */

+
+   Programs that use <stdbool.h> should be aware of some limitations
+   and standards compliance issues.
+
+   Standards compliance:
+
+       - <stdbool.h> must be #included before 'bool', 'false', 'true'
+         can be used.
+
+       - You cannot assume that sizeof (bool) == 1.
+
+       - Programs should not undefine the macros bool, true, and false,
+         as C99 lists that as an "obsolescent feature".
+
+   Limitations of this substitute, when used in a C89 environment:
+
+       - <stdbool.h> must be #included before the '_Bool' type can be used.
+
+       - You cannot assume that _Bool is a typedef; it might be a macro.
+
+       - Bit-fields of type 'bool' are not supported.  Portable code
+         should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
+
+       - In C99, casts and automatic conversions to '_Bool' or 'bool' are
+         performed in such a way that every nonzero value gets converted
+         to 'true', and zero gets converted to 'false'.  This doesn't work
+         with this substitute.  With this substitute, only the values 0 and 1
+         give the expected result when converted to _Bool' or 'bool'.
+
+   Also, it is suggested that programs use 'bool' rather than '_Bool';
+   this isn't required, but 'bool' is more common.  */

+     test a longword at a time.  The tricky part is testing if *any of
+     the four* bytes in the longword in question are equal to NUL or
+     c.  We first use an xor with repeated_c.  This reduces the task
+     to testing whether *any of the four* bytes in longword1 or
+     longword2 is zero.
+
+     Let's consider longword1.  We compute tmp =
+       ((longword1 - repeated_one) & ~longword1) & (repeated_one << 7).
+     That is, we perform the following operations:
+       1. Subtract repeated_one.
+       2. & ~longword1.
+       3. & a mask consisting of 0x80 in every byte.
+     Consider what happens in each byte:
+       - If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
+         and step 3 transforms it into 0x80.  A carry can also be propagated
+         to more significant bytes.
+       - If a byte of longword1 is nonzero, let its lowest 1 bit be at
+         position k (0 <= k <= 7); so the lowest k bits are 0.  After step 1,
+         the byte ends in a single bit of value 0 and k bits of value 1.
+         After step 2, the result is just k bits of value 1: 2^k - 1.  After
+         step 3, the result is 0.  And no carry is produced.
+     So, if longword1 has only non-zero bytes, tmp is zero.
+     Whereas if longword1 has a zero byte, call j the position of the least
+     significant zero byte.  Then the result has a zero at positions 0, ...,
+     j-1 and a 0x80 at position j.  We cannot predict the result at the more
+     significant bytes (positions j+1..3), but it does not matter since we
+     already have a non-zero bit at position 8*j+7.
+
+     The test whether any byte in longword1 or longword2 is zero is equivalent
+     to testing whether tmp1 is nonzero or tmp2 is nonzero.  We can combine
+     this into a single test, whether (tmp1 | tmp2) is nonzero.
+
+     This test can read more than one byte beyond the end of a string,
+     depending on where the terminating NUL is encountered.  However,
+     this is considered safe since the initialization phase ensured
+     that the read will be aligned, therefore, the read will not cross
+     page boundaries and will not cause a fault.  */

+
+#ifndef VERIFY_H
+# define VERIFY_H 1
+
+/* Each of these macros verifies that its argument R is nonzero.  To
+   be portable, R should be an integer constant expression.  Unlike
+   assert (R), there is no run-time overhead.
+
+   There are two macros, since no single macro can be used in all
+   contexts in C.  verify_true (R) is for scalar contexts, including
+   integer constant expression contexts.  verify (R) is for declaration
+   contexts, e.g., the top level.
+
+   Symbols ending in "__" are private to this header.
+
+   The code below uses several ideas.
+
+   * The first step is ((R) ? 1 : -1).  Given an expression R, of
+     integral or boolean or floating-point type, this yields an
+     expression of integral type, whose value is later verified to be
+     constant and nonnegative.
+
+   * Next this expression W is wrapped in a type
+     struct verify_type__ { unsigned int verify_error_if_negative_size__: W; }.
+     If W is negative, this yields a compile-time error.  No compiler can
+     deal with a bit-field of negative size.
+
+     One might think that an array size check would have the same
+     effect, that is, that the type struct { unsigned int dummy[W]; }
+     would work as well.  However, inside a function, some compilers
+     (such as C++ compilers and GNU C) allow local parameters and
+     variables inside array size expressions.  With these compilers,
+     an array size check would not properly diagnose this misuse of
+     the verify macro:
+
+       void function (int n) { verify (n < 0); }
+
+   * For the verify macro, the struct verify_type__ will need to
+     somehow be embedded into a declaration.  To be portable, this
+     declaration must declare an object, a constant, a function, or a
+     typedef name.  If the declared entity uses the type directly,
+     such as in
+
+       struct dummy {...};
+       typedef struct {...} dummy;
+       extern struct {...} *dummy;
+       extern void dummy (struct {...} *);
+       extern struct {...} *dummy (void);
+
+     two uses of the verify macro would yield colliding declarations
+     if the entity names are not disambiguated.  A workaround is to
+     attach the current line number to the entity name:
+
+       #define GL_CONCAT0(x, y) x##y
+       #define GL_CONCAT(x, y) GL_CONCAT0 (x, y)
+       extern struct {...} * GL_CONCAT(dummy,__LINE__);
+
+     But this has the problem that two invocations of verify from
+     within the same macro would collide, since the __LINE__ value
+     would be the same for both invocations.
+
+     A solution is to use the sizeof operator.  It yields a number,
+     getting rid of the identity of the type.  Declarations like
+
+       extern int dummy [sizeof (struct {...})];
+       extern void dummy (int [sizeof (struct {...})]);
+       extern int (*dummy (void)) [sizeof (struct {...})];
+
+     can be repeated.
+
+   * Should the implementation use a named struct or an unnamed struct?
+     Which of the following alternatives can be used?
+
+       extern int dummy [sizeof (struct {...})];
+       extern int dummy [sizeof (struct verify_type__ {...})];
+       extern void dummy (int [sizeof (struct {...})]);
+       extern void dummy (int [sizeof (struct verify_type__ {...})]);
+       extern int (*dummy (void)) [sizeof (struct {...})];
+       extern int (*dummy (void)) [sizeof (struct verify_type__ {...})];
+
+     In the second and sixth case, the struct type is exported to the
+     outer scope; two such declarations therefore collide.  GCC warns
+     about the first, third, and fourth cases.  So the only remaining
+     possibility is the fifth case:
+
+       extern int (*dummy (void)) [sizeof (struct {...})];
+
+   * This implementation exploits the fact that GCC does not warn about
+     the last declaration mentioned above.  If a future version of GCC
+     introduces a warning for this, the problem could be worked around
+     by using code specialized to GCC, e.g.,:
+
+       #if 4 <= __GNUC__
+       # define verify(R) \
+           extern int (* verify_function__ (void)) \
+                      [__builtin_constant_p (R) && (R) ? 1 : -1]
+       #endif
+
+   * In C++, any struct definition inside sizeof is invalid.
+     Use a template type to work around the problem.  */
+
+
+/* Verify requirement R at compile-time, as an integer constant expression.
+   Return 1.  */
+
+# ifdef __cplusplus
+template <int w>
+  struct verify_type__ { unsigned int verify_error_if_negative_size__: w; };
+#  define verify_true(R) \
+     (!!sizeof (verify_type__<(R) ? 1 : -1>))
+# else

+dnl
+dnl INCLUDE_NEXT expands to 'include_next' if the compiler supports it, or to
+dnl 'include' otherwise.
+dnl
+dnl INCLUDE_NEXT_AS_FIRST_DIRECTIVE expands to 'include_next' if the compiler
+dnl supports it in the special case that it is the first include directive in
+dnl the given file, or to 'include' otherwise.
+dnl
+dnl PRAGMA_SYSTEM_HEADER can be used in files that contain #include_next,
+dnl so as to avoid GCC warnings when the gcc option -pedantic is used.
+dnl '#pragma GCC system_header' has the same effect as if the file was found
+dnl through the include search path specified with '-isystem' options (as
+dnl opposed to the search path specified with '-I' options). Namely, gcc
+dnl does not warn about some things, and on some systems (Solaris and Interix)
+dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side
+dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead
+dnl of plain '__STDC__'.

+dnl output. (ISO C99, POSIX:2001)
+dnl For example, snprintf nevertheless writes a NUL byte in this case
+dnl on OSF/1 5.1:
+dnl     ---------------------------------------------------------------------
+dnl     #include <stdio.h>
+dnl     int main()
+dnl     {
+dnl       static char buf[8] = { 'D', 'E', 'A', 'D', 'B', 'E', 'E', 'F' };
+dnl       snprintf (buf, 0, "%d", 12345);
+dnl       return buf[0] != 'D';
+dnl     }
+dnl     ---------------------------------------------------------------------
+dnl And vsnprintf writes any output without bounds in this case, behaving like
+dnl vsprintf, on HP-UX 11 and OSF/1 5.1:
+dnl     ---------------------------------------------------------------------
+dnl     #include <stdarg.h>
+dnl     #include <stdio.h>
+dnl     static int my_snprintf (char *buf, int size, const char *format, ...)
+dnl     {
+dnl       va_list args;
+dnl       int ret;
+dnl       va_start (args, format);
+dnl       ret = vsnprintf (buf, size, format, args);
+dnl       va_end (args);
+dnl       return ret;

+              However, doing the test right would require a run-time
+              test, and that would make cross-compilation harder.
+              Let us hope that IBM fixes the xlc bug, and also adds
+              support for this kind of constant expression.  In the
+              meantime, this test will reject xlc, which is OK, since
+              our stdbool.h substitute should suffice.  We also test
