FWIW, XFS 1.0.2 used egcs from Red Hat 7.2 for the 2.4.9 kernel RPMs,
and used gcc-2.96-98 for the 2.4.14 RPMS.

We have found some compiler bugs w/ 2.9[5,6] compilers, but I've also
heard that egcs is exibiting bugs as well.

Some recent changes in the XFS code takes some pressure off the
compiler, so hopefully later gcc will be happier with XFS.

Sorry, no clear answer - compiler bugs are hard to identify.
