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.

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.

; Order segments alphabetically.
; Rather ugly workaround to prevent the automatically generated code segment
; for the large model (filename_TEXT) from enforcing its word alignment
Rename all code segments to names that Turbo C++ would generate 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....

; between _TEXT and the first code segment even though we never emit anything
; into it.

Identify all function pointers referenced from code > introduce a new macro to halve the lines of a far function pointer assignment, hoping that this commit will end up deleting more lines than it adds, because TH03 has lots of those > oh wait, these games mainly use near function pointers > unearth even more new functions in the process Seriously, how many more functions are still hidden in this codebase? And all that just because IDA was not smart enough to begin with.
