I've already submitted a patch to solve that problem:

http://gcc.gnu.org/ml/gcc-patches/2003-02/msg01245.html

It needs cleaning up per your instructions.  I'll see about turning it 
around today.

With that patch in, then another patch, see below, can be used to turn 
off the hash tables, and remove the regression what was put into the 
compiler, while preserving the goodness of the walk.  Does this part 
look ok for 3.3, pending the other work?

Thanks for the help on this.
