[svn-r7269] Purpose:

    Update

Description:
    Revamped the configuration system. The configurations for the Fortran
    and C++ libraries are no longer separate from the "main"
    configuration system. This involved removing the "configure*" and
    "aclocal.m4" files from the fortran/ and c++/ subdirectories. Also
    merging settings in the config/ subdirectories into the main config/
    subdirectory.

    Fortran header files had to be modified a little for Linux. It was
    checking if it was a Linux machine by some #defines, however with the
    -std=c99 switch, these defines weren't there. I added a check for
    some other ones which should be there whether the -std=c99 switch is
    used or not.

Platforms tested:
    Verbena (Fortran & C++)
    Sol (Fortran & C++)
    Copper (Fortran & C++)
    Modi4 (Parallel, Fortran, & C++)
