New Revision: 4503

Modified:
   MOAB/trunk/config/hdf5.m4
   MOAB/trunk/config/netcdf.m4
Log:
Misc configure changes/cleanups:
 o Try harder to get configure correct for netcdf that requires hdf5:
     Common logic to find HDF5 libraries that can be used to 
     get the correct HDF5 lib list if netcdf requires it but
     --with-hdf5 was not specified.
 o Consolidate some logic duplicated in netcdf and pnetcdf tests for
     checking fixed limits for ExodusII compatability
 o Don't bother trying to check for above limits if (p)netcdf.h was
     not found.
 o Do not check for pnetcdf if neither --with-mpi nor --with-pnetcdf
    is specified.  Fail earlier if the latter but not the former is 
    specified.
