Intel compiler works fine. It is the gfortran compiler that doesn't compile. 

Here is the code that fails the search for gfortran compiler:

#elif defined(__SIZEOF_SIZE_T__)
c gfortran
#  define IMESH_HANDLE_T integer*__SIZEOF_SIZE_T__

The reason is that gfortran compiler does not define __SIZEOF_SIZE_T__ on fusion, resulting the error "Unknown compiler".
