I wouldn't bother trying to compile gromacs 4.5.1 with pgi 9 or later.
They broke __m128 compatibility with gcc/intel/pathscale and have a bug
in the compiler that triggers on the __m128 usage in gromacs 4.5.1.
patschale 3.2 and older also fails to build this but the upcoming new
4.0 version (which i'm beta testing) builds fine. No benchmark results
