Let me draw a graph of my experiences of EXE size with Turbo C and DJGPP:

   |            t   d
   |          t d
   |        x                     t = Turbo C
 E |    d t                       d = djgpp
 X |d   t                         x = crossover point
 E |  t
   |t

          Source Size

Hello world is much larger under DJGPP than Turbo C (IIRC, anyway), but
DJGPP created smaller exe's for increasing amounts of code.

Did you remember to strip your executables?

The reason for the larger starting base for djgpp is the number of useful
things it does on program startup, like globbing, large command line passing
(I suppose), response files, and nifty environment settings in djgpp.env

You can remove these features if you want.

This .sig is too long, and not at all funny.  You try seeing it several
times in a row.  Oh, and an `ass' is a cross between a donkey and a horse,
not a body part.
