Fortran: Improve pointer size detection in gfortran on MinGW 

In commit ecd84147 (Fortran: Detect pointer size in gfortran on MinGW,
2011-11-29) we started testing for __SIZEOF_POINTER__ but not all GNU
Fortran compilers define this.  Check also for __SIZEOF_SIZE_T__ which
at least one version of gfortran defines without also defining
__SIZEOF_POINTER__.
