GCC and friends originated under Unix, so they will work even better (if
such a thing is possible :).  I now do most of my programming under
Linux, and it's quite nice that things that are accomplished under DOS
only in hackish ways work natively (`fork', for instance, and `pipe').

DOSEMU works very well.  There was a subtle DPMI bug in DOSEMU 0.98.1
that would make DJGPP programs crash infrequently, but it may well have
been fixed.  I haven't yet installed a later version.  (I also had a
Cyrix CPU then in which I since identified several bugs, so that could
be related as well...)  Other than that, it's easily as useful as real
DOS.
