Hmm, I don't understand how it could have got that far, but can you check if
the failure is a crash in the C preprocessor stage by rerunning the failing
command with '-v' added?
I'm testing a fix for that ATM. Here's a copy of the patch, you might like
to see if it helps.
For more on that, see:
http://gcc.gnu.org/ml/gcc/2009-04/msg00000.html
and following thread.
