[svn-r9684] Purpose:

    Port

Description:
    Initial work for supporting GNU FORTRAN/F95 on FreeBSD.  I think I've
got things mostly set up correctly, but I'm getting an internal compiler
error on one of the FORTRAN sources, so I'm not going to add this configuration
to the daily tests yet.

Platforms tested:
    FreeBSD 4.10 (sleipnir) w/GNU FORTRAN
    Not tested in h5committest
