[svn-r6066] Purpose:

    Improvement
Description:
    if neither -f option nor $HDF5_PARAPREFIX was set, it exited.
Solution:
    Use '.' (current directory) if neither -f option nor $HDF5_PARAPREFIX
    is used.  Try to proceed as much as possible.
Platforms tested:
    only sleipnir since it was a simple fix and was failing in sleipnir
    only.
