Most of the complilation slowness I see under MingGW32 is due to the 'make' program rather than the compiler. Current MinGW make is file name case-insensitive via trying all case permutations. This is super expensive for directories accessed via network drives. When I type 'make' for a GraphicsMagick build with the source on a network drive (Samba) it takes over a minute before MinGW make does anything at all.
I'm not using make, so I doubt that's the explanation. I'll probably start using MingW more since I upgraded to GCC 4 and a 6 Core processor, which brings the compile time down to something a bit more reasonable...
(For illustration, on my project:
VC++6 debug: 28.8s
VC++6 optimize 38.6s
MingW gcc 4.4.0 debug 1m7.4
MingW gcc 4.4.0 optimize 2m10.9
MingW gcc 4.4.0 optimize -j6 41.7
