Zuxy,
you can use MSYS as build-environment. This works pretty well for some
doing this. In fact you can use also linux, cygwin, etc as
cross-compiling host for win64/win32 developlement. The advantage of
msys/cygwin is, that you can directly execute and test your
applications on a 64-bit host. For cygwin you are even able to run
testsuite for 64-bit windows. The later point is the reason why I
stick to cygwin as developement environment.
