Re: [tree-ssa] bootstrap failure on ppc-apple-darwin6.6

[Andrew Pinski <pinskia at physics dot uc dot edu>]

Ok, there are two functions that differ in cppexp.c:
	num_bitwise_op
	num_inequality <-- this is the one that is causing this failure, most 
likely

There are two functions from resource.c that differ also:
	find_dead_or_set_register
	mark_set_resources

Thanks,
Andrew Pinski
