What\'s the difference between the MinGW project and the 32-bit portion of the MinGW-w64 project? Does the 32-bit portion of MinGW-w64 have any relation to x64 at all?
One looks like it "cross compiles", from 64 bit to 32 bit, whereas the other looks native.
That was just a quick look though, so I could be a long long way off the mark here......
EDIT: This is only somewhat true. A better explanation is provided here
