Enable compiling with the mingw-w64 32 bit compiler.

adunstan · adunstan · commit 1a0c76c32fe4 · 2011-12-10T15:35:41.000-05:00
Original patch by Lars Kanis, reviewed by Nishiyama Tomoaki and tweaked some by me.

This compiler, or at least the latest version of it, is currently broken, and
only passes the regression tests if built with -O0.
