I use two or three different C and, to a lesser degree, C++ compilers.
I'm sure you can stack the deck either way, but I'll say in loose terms
that it's *really* hard to stack the deck to allow GCC to "win" a
compilation time contest. Whether or not that is an important criteria
to the GCC team isn't my point; my point is that GCC compile times are
out of line.
I started to included examples, but I'd rather not get into that level
of detaill yet.
