you need to use the cross compiler package
  mingw64-x86_64-gcc-core

/usr/bin/x86_64-w64-mingw32-gcc.exe
replaces the old "-mno-cygwin" usage

Thanks - that worked fine with gmp-6.1.0.

I also had to set some environment variables - eg NM=x86_64-w64-mingw32-nm ,
otherwise configure runs /usr/bin/nm and fails. But this is as expected.

Assuming that gmp supports cross-compiling (which is likely), you can just use the configure option --host=x86_64-w64-mingw32. This will automatically select the right gcc, nm, etc.

I assume that if one wants a 32-bit build, one simply uses the "i686" cygwin
package instead of the "x86_64" one.

Yes.  And then configure --host=i686-w64-mingw32.
