I can not get past this error and build gcc/gfortran with or without bootstrap
enabled.  Latest trunk.

I used the following configure:

../gcc43/configure --prefix=/home/jerryd/usr --enable-languages=c,fortran
--with-cpu=default32  --disable-libmudflap --enable-libgomp --enable-threads

The starting gcc is gcc (GCC) 3.3.3 (SuSE Linux)
