This file has been lying around there for almost three months now, because I
initially couldn't describe its functionality...

And surprisingly, TH01's OP.EXE ends up as the first game executable that has
its seg000 cleared out.

nmlgc 4dc9b9ab4a [JWasm move] Don't use the DIST/CALLMODEL constants for procedures and labels
Once you've actually found the right syntax that makes the assembler just use
the default call type of the current memory model for both procedures (where
it's just "PROC" without anything else) and labels (where it's "LABEL PROC"),
these constants become completely unneccessary, even with TASM.

This library also has dedicated support for transparency, which is used in the
Konngara fight (BOSS8_D*.GRP) and which we couldn't edit during the
development of the static English patches.
But of course, ZUN just had to change the format magic in order to make it
seem unique.

nmlgc 0b34460155 [Reduction] #670-672: e087_Trap
I guess this marks the final demystification of how segment declarations work
and how they are compiled. However, it only really makes sense for anything
outside the TEXT segment, like these floating-point functions. As long as the
slices aren't immediately next to each other, it would still be annoying to
have segment declarations inside of them, since we'd have to copy-paste these
declarations around every INCLUDE directive...

nmlgc 3a1c2fd679 Move the stack segment into its own slice
Saves 141 lines, and we'll need to ASSUME it in the upcoming floating-point
slices.

... and even with EMUL being set up and working, TASM still needs to be hacked
into actually emitting emulator calls for certain instructions.

nmlgc bbd8ff96ab [Reduction] #563-568: Floating-point emulator initialization
Finally - and there was indeed no way around switching to JWlink, as ALINK
v1.6 refuses to link the TH01 executables with a nondescript "Undefined base
seg" message once nec_fpinit.asm is included.

nmlgc ae6c844b25 Ensure the correct amount of padding between the TEXTC and DSEG segments
Since DSEG is *supposed* to be aligned to a paragraph boundary, this should
have never mattered. However, JWlink seems to not obey this segment alignment
in some layer of the linking process.
This now guarantees identical builds with TLINK, ALINK and JWlink.

nmlgc 4ac17ac2a5 Trick TASM into not creating 32-bit default segments
So that's the - admittedly rather weird - solution to the problem that has
been plaguing this project ever since the beginning of the reduction step.
Without any 32-bit dummy segments in the compiled object files, more linkers
will be able to build this project, one of them being JWlink
(http://sourceforge.net/projects/jwlink/).

Still can't rename dseg to _DATA though, as TASM stupidly refuses to accept
any ALIGN directives above a segment's alignment attribute value. TH01's
floating-point data slices already require larger alignments, and we're very
likely to have even more of those in the future.

Also, we're finally defining the Borland C++ model symbols directly in the
code, rather than in my unpublished build batch files. :)

nmlgc 696d7f9476 Identify the missing BSS slice of xxv.cpp
sigdata.c doesn't specify any alignment, so this is the only position that
makes sense.

nmlgc 340c8a792a General cleanup
Mostly moving spurious null bytes, which are actually supposed to denote
alignment, into their associated slices, but also prettying up some of the
very first slices.

nmlgc 1c72d7e242 [Reduction] #548: Floating-point emulation data
Well, we have to start reducing this mess somewhere. The actual reduced
initialization code I've been preparing still fails to compile, and the data
is shared with a number of other components anyway, so...
