Purpose:
Bug fix, code improvement
Description:
Fortran tests didn't cleanup created files. Also HDF5_PREFIX and
HDF5_PARAPREFIX were not used to specify location of the files.
There was a redundant file in the testpar directory that contained
an error reporting function used by both serial and parallel tests.
Solution:
Created library h5test_fortran.a that contains functions used by the
serial and parallel tests. It includes Fortran and C functions that
may be called from Fortran programs to report errors, to modify
file names and to cleanup files after run. Modified test code to
use new functions.
Platforms tested:
Linux 2.2 (eirene) serial
IRIX64 (modi4) parallel with HDF5_PREFIX and HDF5_PARAPREFIX set to $SCR
Solris 2.7 with mpich 1.2.4 with HDF5_PARAPREFIX set to /tmp/epourmal
