Comment (by rhaas):

 Replying to [comment:1 knarf]:
 > The HDF5 thorn within Cactus builds with Fortran support, so that this
 should be available everywhere. A problem with that should be reported. On
 the other hand, converting the fortran reading routines to C would not be
 hard. That would also be a solution.

 I had written a set up C stubs for the HDF5 routines that EOS_Omni uses
 some time ago (the patches still apply, with the testing patch shifting by
 a line or so). Mostly these were written because libhdf5 does not compile
 with the CFLAGS settings I like to use (it uses implicit declaration of
 functions).

 Since others seem to have trouble getting the FORTRAN interface to work as
 well, these might be useful.

 The stubs are trying to be careful about mapping HDF5 types to Cactus
 types, but they essentially cast all hid_t types to CCTK_INT (and try to
 test that this actually worked without loss of information).
 Also I hardcoded some options in the stubs that used to be passed as
 parameters (mostly because it avoid having to somehow provide #defines for
 named constants).

 I have tested them (using the second patch) by reading in Chen's EOS table
 that Christian provides on stellarcollapse.org and comparing the ASCII
 dump of the read in table.
