64-bit versions of Windows will run both 32-bit and 64-bit executables
and DLLs. The main compatibility issue is that 64-bit versions of
Windows need 64-bit device drivers; user-space code shouldn't be
affected.

Regardless of the version of Windows on which it runs, the stock MinGW
distribution will generate 32-bit code which will run on either 32-bit
or 64-bit versions of Windows.
