I don't have a lot of experience with mingw32, but to the best of my knowledge, it's based on older versions of gcc (4.6?), and lacks 64-bit support
Ehsan, did you forget that there would be no memory problem with 64-bits MSVC PGO builds ?
The trouble with going 64-bits is that the jit would then see some significant regression, for cache pressure/instruction set related reasons (ie gcc won't do it any better, probably worse)
