[Bug fortran/40583] automatic preprocessing for .F90 or .F95 files fails with cc1 error (output filename specified twice)

[thomas dot orgis at awi dot de]

------- Comment #2 from thomas dot orgis at awi dot de  2009-06-29 12:51 -------
Thanks for confirming that it _should_ work.
Now the question is: What is wrong with the installation on my system so that
it does not work?

I see that gfortran is apparently trying to preprocess the .F95 files, but that
cc1 call goes wrong.
Is this perhaps a problem with installing gcc, g++ and gfortran in separate
steps? I mean, the preprocessor itself does not have a problem with
f95-cpp-input ... so that does not seem so plausible.

This is essentially our gfortran install script -- is there something wrong
with that?

# end of script

The specs_fortran file, being incorporated into the common specs file looks
like that (I am wondering: Are we supposed to ship that file -- I did not write
the build script myself)?):
