Gcc 2.6.3 produces pretty good 386 code, 2.6.3i the pentium 'unofficial'
release is even better. Watcom is better still 8). Gcc is capable of optimising
16 bit (and even 8bit - see the 68HC11 gcc) but nobody has done gcc with a
DOS 16 bit target.

No need. The support is already include with the DJGPP wattcp library.
