If your program is a "vanilla" program (like a compiler!), all that is
necessary is to relink the .OBJ files with the OS/2 runtime library instead
of the DOS runtime library. Of course, if you call BIOS functions directly,
access hardware directly, etc., there will be additional work involved.

Note that it is very difficult to port code that uses the mouse to text
mode OS/2. The MOU functions under OS/2 are totally different and
significantly less capable than the INT 33 mouse api under DOS.
