Sorry about this, but I don't have any real objective numbers. I was
just trying to give a general feeling, and what I wanted to say was that
I was impressed by the speed gain. But of course the comparison is not
really fair for Borland C 3.0 since this compiler only compiles to
16-bit code.

Speed is always difficult to quantize, therefore I tend to use subjective
measures.

I think this is true for ALL programs. But I also think DJGPP is a very good
general purpose C compiler. Watcom is probably also a very good general
purpose compiler (I wouldn't know, I've never used it) but Watcom is expensive
in comparison with DJGPP.
