gfortran.texi: Add mixed-language programming...

2009-06-03  Tobias Burnus  <burnus@net-b.de>

        * gfortran.texi: Add mixed-language programming, mention
        varying string lengths, some clean up of introduction parts.
        * intrinsic.texi (instrinsic modules): Create @menu for
        * subsections.
        (ISO_C_BINDING): Support ISOCBINDING_INT_FAST128_T.
        * libgfortran.h: Comment to rember to keep gfortran.texi in
        * sync.
        * iso-c-binding.def: Support ISOCBINDING_INT_FAST128_T.
