--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> --- "Specify explicitly the language for the following input files (rather than letting the compiler choose a default based on the file name suffix). This option applies to all following input files until the next -x option. Possible values for language are:" "Following input files" seems confusing the first time I read it but the second time I read it, I read it as the input files that are after the -x option rather than the types listed below. Hopefully that makes better sense.
