I updated the tree (no local patches), and reconfigured and bootstrapped mainline.  The config is:

../gcc/configure   --prefix=/home/jlquinn/gcc/dev --with-cpu=power4 --with-gcc-version-trigger=/home/jlquinn/gcc/dev/gcc/gcc/version.c --enable-languages=c,c++,java

This is on AIX 5.2 pl 3, using xlc.
