Add << prefix to force 5 bit offsets in indexed modes
Rounding out the compliment of operand size prefixes, we now have "<<" to
mean "force 5 bits". According to Steve Bjork, this was the "official" way
to do this since 1980. However, I have no official Motorola source for
that. It does suggest that the choice of "<<" is consistent with other
(historical) assemblers, though.
Either way, it seems the most logical choice while avoiding any conflicts
with legal source code, so "<<" it is.

With LWTOOLS 4.0, a substantial reorganization of the project has occurred. This document serves to explain the reasoning behind the various changes. The most obvious change is that the gnu auto tools have been eliminated. While they proved useful for initial distribution of the software, particularly for construction of the win32 binaries, they have since proved to add an unacceptable level of complexity to every aspect of development from merely tinkering with source files to doing complete releases. Thus, the auto tools have been ditched in favour of specific hand tuned help where required. The other substantial change is that the source code repository has been recreated from scratch. The old repository was full of cruft from various revision control systems that were used over the years (CVS, Subversion, and Mercurial). It was felt that starting a new Mercurial repository with a completely clean slate would simplify matters substantially. Thus, the old repository now serves as an archive.
