OK.  I see that you have a patch to alter the configure script for
HDF5 that removes AC_TRY_RUN tests.  It's also possible to just set
those cache values on the configure command line:

  configure ... hdf5_cv_gettimeofday_tz=no ...

Either way will work, but if you set the values on the command line
instead of modifying the configure.ac file, then you shouldn't have to
regenerate the configure script and you can eliminate a patch file.

It currently means both.  We really need to have a third option, which
is to build with x86_64-w64 (for 64-bit pointers) but to use the usual
32-bit integers for Fortran indexing.  I intend to do that by
introducing another option, one to control the compiler and one to
control the 64-bit integer indexing option.
