Hi, everybody...
I've tried both, the latest version of EMX/GCC (0.8f) and DJGPP 1.09 wit
LIBGRX 1.02.
                   EMX/GCC                    DJGPP
Debugger           ++   (GDB)                 + (DEBUG32)
Graphics           +-   (320x200x256)         ++ (LIBGRX)
Libraries          +                          ++
curses             BSD                        y
windowing lib      y                          ?
ANSI C             y                          y
C++                ?                          y
Objective C        ? (y, I believe)           y
OS/2               y                          n
virtual memory     y                          y
DPMI               n                          n
VCPI               y                          y
QEMM386, 386MAX    y                          y
low hardware acc.  +                          ++
int86x()           +                          ++
comp. speed        -                          -
exec. speed        ++                         ++
docs               +                          ++ (libraries --> - !)

I don't want to tell you some lies, and I don't think, my opinion
is the only opinion, but these list results from the impressions
I had experimenting with both compilers at the same time.
Both compilers have their own highlights (EMX/GCC --> OS/2 support,
GDB, clear docs for libraries;  DJGPP --> rich libraries, excellent
graphics support for SVGA) and it's difficult to choose one and only
one of them. EMX is great for porting text-based applications from
UNIX to OS/2. DJGPP is great for porting nearly every C code to DOS
(but ONLY DOS !).

If GDB would work together with DJGPP, a lot of people I know would
choose DJGPP instead of EMX/GCC. If there'd be a graphics lib similar
to CBGRX for EMX/GCC, maybe I'd switch to EMX/GCC.

Any comments and corrections to the check list are appreciated and
welcome.
                   ...Matthias
