Well, lets begin.
First at all, let make source compilable by TC and BC. Done (some
source cleans and one BUG-fix) - see attachment.
Now, let re-create MISSING build subsystem. Done - I prepare batch
files, makefiles and configs, similar to kernel subsystem. Now EMM386
compilable by TC and BC in same manner, as kernel. How (where) send you
these files?
PS: Interesting to compare result:
TC BC
EMM386 39122 38658 (BC 464 bytes shorter)
HIMEM 12969 12995 (BC 26 bytes longer)
