Free Fortran compiler for Mex on 64 bit Windows

I was wondering if anyone knows a way to get a free Fortran compiler to work compiling 64 bit mex files on Windows.

I have no trouble with Intel Fortran. When I last tried I could get gfortran working with 32 bit Matlab (with GNUMEX) but couldn't get anywhere with 64 bit.

If anyone else has got this working or heard of it working I would try again... or any other suggestions...

Note: there are no supported free Fortran compilers for MS Windows.

Thanks - I know that. But I have had much success with 'non-supported' combinations in practise - eg Intel on Mac and Linux, gfortran and gcc on windows (just not 64 bit). So my question is whether any one else has had success or found a solution.
