That file should be in your case in
/var/tmp/43/build-159/powerpc-unknown-linux-gnu/libgfortran/config.h
         ^^^^^^^^^^^^ <- this might be different,
         depending where you build gcc/gfortran; this was the
         directory used in your bug description (comment #0)

The file is generated at configure time and thus specific to the system where
gcc/gfortran is build.

On my system (x86_64-unknown-linux-gnu, but also glibc-2.6), I have in the
equivalent file:

#define HAVE_LLROUND 1
#define HAVE_LLROUNDF 1
#define HAVE_LLROUNDL 1
#define HAVE_LLROUND 1
#define HAVE_LLROUNDF 1
#define HAVE_LLROUNDL 1

I would expect that your config.h has the same entries (as we both use a recent
glibc), but it would be great if you could confirm this.

As FX wants to check whether the C Library (glibc) works correctly, it should
not matter; but if you have the choice I would use gcc 4.3.0.
