Autoconf refers to the parts of the triplet as CPU-TYPE-MANUFACTURER-OPERATING_SYSTEM
config.guess returns x86_64-pc-mingw64

I don't really buy the argument that mingw32 and mingw64 are ABI compatible ... maybe it's technically/theoretically true for some definition of ABI, but it's praqctically false since in practice the two are tied to different processor architectures.
Certainly Autoconf (in the form opf config.guess) does not believe it.

Still, since the mingw64 people seem to have chosen to do it this way, and presumably can't easily change, and the autoconf people probably don't want to change a standard that they 'own', I guess we will need to find a way to work around the fact that, depending on where you get the triplet from, it might say the system is mingw64 or might say it's mingw32.
We will need to find where gnustep-make looks for either, and put additional checks in place for other parts of the triplet.
