CG>    With one of my programs, made with Watcom C/C++ 10.6, if I optimize by
CG>"unrolling the loops", my program will not run properly in
a DOS window unde
CG>OS/2.  Yet it runs fine in a true MS-DOS session.  Anyone have any ideas? :)

You didn't say what wasn't working, but most likely you've got a wacky
pointer that is trashing part of OS/2 dos, but not part of MS-DOS since
they are quite different in where they put everything.  If this is a
text mode program, try compiling it as an OS/2 fullscreen app, you'll
probably get a GP fault on the line that is messing up.  Watch for
NULL pointers, or any str* or mem* functions, they overwrite memory all
the time if you aren't very careful.
