[The problem is bootstrapping gcc 2.95.3 with gcc 3.2 gives
comparison failures.]

Are you sure this signifies a bug in gcc 3.2, as opposed to
a bug in gcc 2.95.3 that simply gets exposed by being compiled
with 3.2?  E.g. maybe gcc 2.95.3 somewhere violates aliasing
rules ...

I have seen a similar case where the gcc part of SPECint
(I think this is a 2.7.2 or so) fails when being built
with gcc 3.x, because of aliasing problems.

Does the bootstrap work when stage 1 is built with
-fno-strict-aliasing?

That assumes gcc 2.95.3 is not known to produce wrong code ;-)
