Not a bad suggestion. I think we were sort of hoping that somebody who
cares about hdf5 will do the update, but maybe nobody cares enough. If
you would like to write a test program that detects the version, I
could include it in configure.

Use --without-hdf5. Maybe, given the state of HDF5 support (only
obsolete version is supported), we should make this the default and
not warn about it. What do you think? That would mean much less work.

Please a start a fresh thread or revive the old one, I'll take a look.
