No, he's building glibc-2.2.5, not 2.3.2.  Maybe we need a similar patch for 2.2.5?
But I don't think so; here, powerpc-405 / gcc-3.4.1-glibc-2.2.5 bulds just fine.

Odd - mipsel builds fine here with gcc-3.4.1 and glibc-2.3.2 as
currently patched.  I don't seem to need to extend the patch.

Can either of you give me a recipe for reproducing the
problem on mipsel or ppc405 using vanilla crosstool-0.28-rc28?

I think I just took the patch directly from glibc cvs.  I prefer
doing it their way when possible.  Have you checked to see
if they addressed your issues in glibc cvs?  If so, I'd
prefer to take their change.  (If not, maybe you need to
submit the change to them?)
