Configuration
-------------
- * The hdf5.h include file was fixed to allow the HDF5 Library to be compiled
- with other libraries/applications that use GNU autoconf.
- * Configuration for parallel HDF5 was improved. Configure now attempts to
- link with libmpi.a and/or libmpio.a as the MPI libraries by default.
- It also uses "mpirun" to launch MPI tests by default. It tests to
- link MPIO routines during the configuration stage, rather than failing
- later as before. One can just do "./configure --enable-parallel"
- if the MPI library is in the system library.
