NASM behavior with regards to e.g. extern $foo.
Unfortunately this makes yasm start not matching NASM behavior with regards
to the RDF module directive. In NASM, module $foo results in a literal $foo
reference; yasm now requires either a double $ (e.g. $$foo) or quotes (e.g.
"$foo"). The special case for section (section $foo --> literal $foo) is
still present, but keeping this for other directives is extremely difficult.

bytecode multiple.
strucsize.asm tests both creation and instantiation of a nested structure.
[1751] and [1752] fix bugs found during the testing of the instantiation
portion of this testcase.
A side effect of this change is that some errors are found in different
phases, and the error messages are slightly different. Split
reserve-error.asm testcase into two parts to still get full coverage.

the C function and data structure wrappers for Pyrex. We now require
Pyrex 0.9.5 to build the Python wrappers, as only >=0.9.5 has working
weakref support. We actually need 0.9.5.1, but it's not yet released
(0.9.5 has a crash bug in enum wrapping that we trigger).
Pyxelator works a lot better with non-anonymous enums/structs, so libyasm
has been scrubbed for this.
Next step: full Yasm data structure inspection.

timestamp to determine if the object file has been updated, so not setting it makes for
bad behavior (the object file gets updated, but when the executable is linked it uses the
older "internal" version).
To keep tests passing, check an environment variable (YASM_TEST_SUITE); if this exists, the
timestamp is set to 0. Set this environment variable in out_test.sh.

%include "%SOMEVAR%/subdir/file.inc"
Multiple %VAR% are supported in a single %include.
Undefined vars are not expanded.

This adds 3 object format keywords: macho, macho32, macho64. These work in
the same way as elf, elf32, and elf64. The object format is still a work
in progress; amongst other things it does not yet support full cross-section
references (othersym1-othersym2), dynamic linking, or GAS input syntax. We
will continue to improve and work on these features in the near future.

(such as the common .note.GNU-stack section). While Yasm allows such section
names by enclosing with double-quotes, NASM allows this, so for compatibility
it makes sense for Yasm to as well.

parser with one token of lookahead. This allows for better error handling
and proper handling of things like "xxxx"/5. There may be a minor speedup
but it's probably a wash.
Still TODO:
- Unify the expression parser with the NASM preproc one.
- Change the GAS parser to recursive descent.
Only had to change one test result; this is due to re-ordering of symrec
creation versus symrec use in data expressions such as x db y. With the
Bison parser, the symrec use (y) would come first, now the symrec creation
(x) comes first.

such that only ELF and COFF actually handle .ident; all other object
formats silently ignore it.
In Win32/Win64, the .ident contents are dumped into the .rdata$zzz section
rather than the .comment section as in COFF and ELF; this is due to the
fact the GNU linker for Win32 is broken and puts .comment in the output
executable as a separate section, breaking the executable. The .rdata$zzz
name matches that used by GAS to work around this same linker bug.

(sym in other section)-(sym in this section) rather than just
(sym in other section)-(curpos) (e.g. sym-$). Unfortunately supporting
this required precbc to be flowed down to the value_finalize functions,
but it's relatively reasonable to do so, as all of the _finalize() routines
have access to precbc.
