That's only the 64 bit compiler of MinGW-W64. That project also
publishes a 32 bit compiler, which is what Yaron proposes to use instead
of the compiler provided by mingw.org, IIUC. I concur with him, FWIW.

IMO switching from mingw.org to mingw-w64 as the 32 bit MinGW toolset
makes sense, for the reasons given by Yaron.
