annotate lwasm/instab.h @ 374:8e25147c2aa8

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Clean up various "externs" Apparently some compilers seriously choke on the "extern" keyword in some circumstances where GCC does not. Remove most instances of "extern" to guard against that. Thanks to Erik G <erik@6809.org> for the patch.
