If you want to write OS/2 programs, then you should go with emx/gcc.
emx/gcc can create native OS/2 programs.  djgpp compiled programs
cannot run under OS/2 sessions, but only in OS/2 DOS compatibility
box in which programs have to suffer with DOS limitations.

There is a separate mailing list for emx/gcc: 

	emx AT iaehv DOT nl

To subscribe, send a message "subscribe emx your-email-addr" to 

	majordomo AT iaehv DOT nl

I haven't heard of 'rmx' but 'rsx'.  If you meant 'rsx', it is not
for OS/2, but it makes an emx/gcc-compiled program to be able to
run under DPMI (like Windows's DOS box, or OS/2's DOS box).
emx/gcc can generate DOS prgrams depending options, and such programs
cannot be run under DPMI without using 'rsx'. (However, the primary
target of emx/gcc is OS/2 native programs, not for DOS.)
Ask more questions to emx list.
