So, I don't see that you have cygwin gfortran installed, so I assume the
gfortran below is mingw64-x86_64 targeted one?

So this doesn't seem right. Linking the cygwin libX11 with objects built
with a mingw64 targeted compiler isn't going to work correctly.
I'm afraid we don't provide packages for mingw64 X libraries, so I guess
your alternatives are to build those yourself, or to build everything
using a cygwin targeted compiler.
