I strongly suggest you use GCC 4.8 or newer.
This:
http://sourceforge.net/p/mingw-w64/wiki2/Cross%20Win32%20and%20Win64%20compiler/
says 4.5.1 is supported. CentOS has 4.4.7 installed and I didn't want my
Windows-targeted compiler to be much advanced from my regular one. I can
try something more recent, though.

It seems like the installation instructions should probably be updated
with this information. At the very least, the incorrect ones should be
taken down.
I will take a look at these scripts, though.

I'm using them for now while trying in parallel to get 64 bit working.
