Thanks for testing the patch, it has now been committed.

It seems you have cvsup'ed at a bad time.  The -fformat-extensions
option is a FreeBSD-specific (and NetBSD, I've been told) option, and
is not in GCC baseline.  It has been merged back in revision 1.24 of
src/contrib/gcc/toplev.c.  Can you check that you have the latest
version of this file?  If you don't just re-cvsup and try again.

This patch is incorrect, as should be obvious after the explanation
above.
