This bug has already been reported twice, as described here
http://gcc.gnu.org/ml/gcc-patches/2002-01/msg01398.html

I described how to fix it in ppc-specific fashion (pointed to from above)
but I don't think that's really correct.

Franz Sirl posted a target-independent attempt here
http://gcc.gnu.org/ml/gcc-patches/2002-02/msg01568.html

which is awaiting approval.  I really wish one of the reload experts
would look at this problem.
