 Then again, a lot of a `full' DJGPP install is source, which isn't even
an option with MSVC. (and yes, source is useful to have. Only occasionally,
but when it's useful, it's essential..)

 Also, DJGPP is completely and totally clobbered if you don't have a disk
cache; install smartdrv (or whatever) and the speed improves by what feels
like an order of magnitude. MSVC has Windows to help with the file management
and speedup; DJGPP has, well, DOS.

 DJGPP is _way_ slower than GCC running under Linux, despite the fact that
it's essentially the same program, give or take the interface to the operating
system. DOS stuffs the speed up completely. (no, this isn't a "DOS is 
slower than Windows" comment -- just that DOS doesn't have disk caching
built in, Windows/Linux does -- and for compile speed, disk caching makes
an awful lot of difference.)
