[patch] Have cc1 define a __GFORTRAN__ macro when -lang-fortran is used

> Attached patch makes cc1 define the __GFORTRAN__ macro as equal to 1
> when it is passed the -lang-fortran option. This option is used when
> the driver decides (or is told ) to preprocess a Fortran file. The
> changes are minimal: we already had a lang_fortran variable that says
> whether -lang-fortran was passed, so we simply need to make it visible
> from c-cppbuiltin.c, where we actually define the macro.
>
> The patch is bootstrapped with C and Fortran on i686-linux. An earlier
> version regtested fine, and this regression-test for this one is
> almost done.
>
> OK for mainline?

         * gcc/c-opts.c (lang_fortran): Make it non static.
         * gcc/c-common.h (lang_fortran): New prototype.
         * gcc/c-cppbuiltin.c (c_cpp_builtins): Create a __GFORTRAN__
         if the -lang-fortran option was passed by the driver.
