While building llvm-gcc-4.2 with fortran support on Linux/x86 (32 bit), I'm
running into a failing assertion when libgfortran is being built (see below).

I'm using SVN head for both llvm-gcc-4.2 and LLVM. I have adjusted llvm-gcc-4.2
slighty using the patch at
http://www.nabble.com/fixincludes-for-glibc-'inline'-non-C99-conformance-t2564711.html,
 but I don't think that is related to this, because the patch fixes a
C++-related problem.

LLVM is built using './configure' and 'make', llvm-gcc-4.2 is configured with
'../llvm-gcc-4.2-patched/configure
--prefix=/work/LLVM/LLVM/llvm-gcc-4.2-bin-patched
--enable-llvm=/work/LLVM/llvm-obj --enable-languages=c,c++,fortran
--enable-checking' and built using 'make'.

Is there something missing in LLVM regarding AST-support? (just guessing here,
I saw llvm-convert is converting from AST to LLVM code).
