Looks like the MMX switch somehow enforces 32-bit mode for this
particular file. You can try to disable MMX because it is optional for
pixman and does not affect its functionality in any way.

Maybe it's even a good idea to have MMX off by default in Makefile.win32
but the decision is up to Windows users (I'm not one of them).
