re PR driver/11417 (fortran options warned about in cc1 when *.F or -x f77-cpp-input)

PR driver/11417
	* c-opts.c (permit_fortran_options): New.
	(c_common_init_options): Accept fortran front end options if
	it looks like we might be preprocessing Fortran.
	(c_common_handle_option): Don't reject switch if permit_fotran_options.
