Given that particular choice, it's not hard to decide.  DJGPP is at
least twice as fast (and takes twice as long to compile).  Turbo C is
good to learn on because of its online help and quick compilation, but
if you use DJGPP with RHIDE it'll be almost the same.

How's it compare to other compilers?  About 3 years ago, I used a
certain CPU-intensive program that was only available in .EXE form. 
Originally it was compiled with Turbo C.  Then the author switched to
Watcom C, and the speed doubled.  A few months later, he switched to
DJGPP for an 8% speed increase.

I don't know much about current commercial compilers.. I hear Visual C++
5.0 is the fastest Windows compiler, because Microsoft keeps secrets
from the other companies.  I've also heard Watcom runs faster than DJGPP
on Pentiums, but every game I've seen that uses it has alot of quirks..
