This is an updated version of my patch taking care of warnings when cc1
is called from gfortran to preprocess fortran source. I used a
different (and in my view, cleaner) approach: Fortran options are not
marked as C, but when preprocessing fortran source, cc1 is given a
-lang-fortran flag, which makes the preprocessor not warning about use
of Fortran options.
Tested on i686-linux, with both languages=c and languages=c,fortran.
The current behaviour for compiling C and Fortran in a single
command-line is kept. Regtested for languages=c, regtesting in progress
for languages=c,fortran -- howdy, how long is that C testsuite to run!
:(
OK for mainline when it reopens before branching?
