I have mingw tests for mingw-32, mingw-w64 gcc 4.9, 4.8, 4.7, 4.6, 4.5,
and 4.4. Also the mingw-gcc that ships with Qt 5.4, Qt 5.2 and Qt 4.

I don't recall everything I did to get it working, but I'll fire one
back up tomorrow.

As I recall, clang wouldn't build one kind of library (dynamic or
static, I don't recall which), and that killed the results. Has that
