[Regression] Explicitly request 16-bit default segments when using .MODEL Whoops, turns out that the build has been broken on TASM32 version 5.3 (the one in the DevKit) ever since 7897bf1. In contrast to version 5.0 (which I use for my development), 5.3 actually defines 32-bit segments if you specify a .386 CPU before using .MODEL. That might have been the reason for the .286 workaround all along? Turns out there's the USE16 modifier, which makes this much more explicit than switching CPUs.

Move common directives and includes to a separate include file Note that .386 needs to come before .MODEL, and is therefore not included in ReC98.inc. Causes, um, weird label errors otherwise.

Finally use standard segment names everywhere And I guess we just have to ignore and disable that segment alignment warning for TH01. It's not like this changes anything in the binary.

_TEXT segment word public 'CODE' use16
assume cs:_TEXT
Let Turbo C++ link in the Borland C/C++ runtime for the main EXE files 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.

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.
