Thanks to the LOCALS directive, we do need to break compatibility to TASM at
one point after all. This is the rest we can reasonably change to get at least
through JWasm's first pass without errors while maintaining compatibility to
TASM.
Includes:
* the OPTION syntax to switch in and out of floating-point emulation mode
* REP CMPSB → REPE CMPSB
* Hacks for two 80-byte short jumps
* lack of support for floating-point stupidity ♥
as well as other issues that I covered in previous commits and overlooked in
some files.
From the TASM manual:
"NEAR labels defined with the colon directive (:) are considered block-scoped
if they are located inside a procedure, and you've selected a language
interfacing convention with the MODEL statement. However, these symbols are
not truly block-scoped; they can't be defined as anything other than a near
label elsewhere in the program."
MASM's own local label syntax - declaring labels using @@ and then jumping to
the next and previous @@ using @F and @B - is obviously too limiting for any
longer function, and is not even supported by TASM unless we switch it to MASM
mode completely.
While this is indeed ugly, it only affected 16 files, which is way less than
what we would get in a TASM build without LOCALS. In comparison to having a
modern, cross-platform assembler, that really is a small price to pay.
Looks like the 'pal98 grb' string was merely copy-pasted from the respal
module and isn't actually used by the function, which means that we don't have
to work around a naming collision after all.
