Since you're already using MSVC, albeit an older version,
it probably wouldn't be a huge amount faster.  I'd guess
10% at the most (I could be very wrong! :).

I believe MSVC is about 15-20% faster than GCC/PGCC/etc.
I don't know about Cygnus, but it's probably a bit slower
than MSVC also. [This is from compiling Crafty, YMMV]
