Many thanks to http://bytepointer.com/tasm/index.htm for providing a
better searchable resource for TASM's default `LEA imm16` → `MOV imm16`
optimization, which we initially had to hack around here.

Well, duh, of course, we *can* do this in order to allow decompilation to be
started at the end (not the beginning) of any segment. In fact, if we hadn't
done this, we would have had to start by moving _TEXT out to libraries....
This took long enough, so we're not covering the COM files right now. Like, I
can't even tell how you're supposed to work around the forced word alignment
for the _TEXT segment. Guess we'll just have to decompile all of these in one
go, just like we did with ZUNSOFT.COM.
Also, it really seems as if we're merely trading one ugly workaround for
another in our quest for identical binaries.
Turns out we're not quite done with reduction yet, as there still are a bunch
of macros in master.h that #define PC-98-specific hardware constants and I/O
ports.

Seriously, how many more functions are still hidden in this codebase? And all
that just because IDA was not smart enough to begin with.
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code, rather than in my unpublished build batch files. :)
