This patch makes the GCC extension __float128 (_Complex) available in
the C bindings via C_FLOAT128 and C_FLOAT128_COMPLEX.
Additionally, I have improved the diagnostic for explicitly use
associating -std= versioned symbols. And I have finally added the
iso*.def files to the makefile dependencies.
As usual, with -std=f2008, the GNU extensions are not loaded. I have
also updated the documentation.
OK for the trunk?

PS: If you think that C_FLOAT128/C_FLOAT128_COMPLEX are bad names for
C's __float128, please speak up before gfortran - and other compilers
implement it. (At least one vendor is implementing __float128 support
and plans to modify ISO_C_BINDING.) The proper name would be
C___FLOAT128, but that looks awkward!
