Correct. (I guess there will be a 64-bit Cygwin eventually, but there
are no plans for it at the moment.)

Yep, sounds like a good use case for a hypothetical 64-bit Cygwin.

Yes, but they're obviously off-topic for this list. The mingw64
project may help with you that.

I think the list would be interested in hearing what problems exactly
you're having though. Your original message seemed to say that you had
successfully used Cygwin's mingw64-x86_64 toolchain to build your
program.
