Agreed.

I could try, but my understanding is that they are not interested on
doing that, for multiple reasons. One of them is that, in theory, you
could use the MinGW-w64 compiler with the MinGW headers and libraries.

__x86_64__ is about the processor. It is also defined by gcc 4.8.2 on my
Kubuntu x86_64. Of course, being MinGW on x86_64 implies Windows 64. But
I've seen quite a few patch submissions about ARM support on the
MinGW-w64 ml, so an hypothetical Emacs compiled for Windows ARM 64bits
by MinGW would fail the __x86_64__ test. If that Emacs comes to light,
we probably would need to determine what's the right thing wrt
ALIGN_STACK, though.

So in this specific case __x86_64__ does not harm, but it is superfluous
on the presence on _WIN64.

Thanks!
