The following patch is required, because gfortran nowi (>= 4.3?) adds a final _ to all symbols by default. The patch is required also with cfortran.h 4.4. Another problem is due to an oddity in fortran/Makefile.am which requires a mandatory --with-hdf5=<path> among other options (in my case path=/usr). That could be easily fixed also in the automake file. That fix seems appropriate to me, because HDF5 support is required but a path specification is not mandatory. The final result without this patch is a lot of UNDEF symbols and a broken Fortran support.
