[Bug fortran/36376] New: -cpp -save-temps passes unknown options to f951

[dfranke at gcc dot gnu dot org]

http://gcc.gnu.org/ml/fortran/2008-05/msg00354.html, issue 1:

When I compile a .F90 file with -save-temps, I get:
f951: warning: command line option "-fpch-preprocess" is valid for
C/C++/ObjC/ObjC++ but not for Fortran

[Bug fortran/36376] -cpp -save-temps passes unknown options to f951

[dfranke at gcc dot gnu dot org]

------- Comment #1 from dfranke at gcc dot gnu dot org  2008-06-07 08:30 -------
There are two ways to solve this: 

 (1) move "-fpch-preprocess" from gcc.c(cpp_options) into, say, cpp_c_options
and add cpp_c_options everywhere where cpp_options are used but fortran
 (2) duplicate gcc.c(cpp_options) into fortran/lang-specs.h but omit
"-fpch-preprocess"

Which solution would be preferable?

        * lang-specs.h: Pass on -i* options to f951 to (probably) report
        them as unknown. Duplicate gcc.c (cpp_options), but omit
        -fpch-preprocess on -save-temps.
