In some ways it is worse since there isn't even a standard ABI. You can
mix Clang and GCC when they use the same STL implementation. I
wouldn't try that with any two members of the Fortran compiler family...

My point was mostly that g95 is limited to libgcc_s (which is known to
produce problems) and libf95 (which is Fortran specific, so contained).
The same can't be said for the gfortran options.
