	I don't know for sure, but I think that part of the problem is
that egcs-1.1 uses "register_operand" predicate for a number of GOT
patterns in the machine description which should be "gpc_reg_operand".
This change already had been applied to the EGCS development sources a
while ago, but was not change in the egcs-1.1 updates.  It will be
included in the forthcoming egcs-1.2 release.

	Maybe someone who has built a recent version of the development
sources for powerpc-linux can try to recompile your examples to see if
they still fail.
