[Fortran-Experiments] commited c_kind_params.f90 patch; merged from trunk

[Tobias Burnus]

Hi,

First, I committed the c_kind_params.f90 patch (i.e. don't test
c_int_fast8_t as they are "-2"):
rev 123399, http://gcc.gnu.org/ml/gcc-cvs/2007-04/msg00008.html

Secondly, I updated from the trunk (rev 122938-123028):
rev 123409, http://gcc.gnu.org/ml/gcc-cvs/2007-04/msg00018.html

Bootstrapped on x86-64/Linux and regression tested (-m64 and -m32) with
now no failures.

I did not merge further as I had some problems with Paul's
(namespace)->derived_types to gfc_derived_types change; I tried to fix
symbol.c, but I get a failure with:
$ gfortran iso_c_binding_rename_1.f03
    if(.not. my_c_associated(cptr1)) then
                            1
Error: Type/rank mismatch in argument 'c_ptr_1' at (1)
