I'm quite sure at some point someone told me the exact opposite of
this, whcih is why you see what you see in nt/inc/.

It is a PITA that the MinGW64 compiler doesn't define some clear-cut
macro for that without the need to include headers.  IME this is a
terrible maintenance headache in the long run.  Perhaps you could ask
the MinGW64 developers to change their mind about that.

What about __x86_64__, does it perhaps fit the bill already?

Done in trunk revision 118105.
