Interesting!
Can you file a bug at http://sources.redhat.com/bugzilla
describing the problem and what you had to do to fix it?

Thanks.  I wonder if that applies to the ppc405, too.

Ah, but I do.

The 'right' way to fix this might be to use the
sanitized kernel headers by adding the line
LINUX_SANITIZED_HEADER_DIR=linux-libc-headers-2.6.11.2
to your .dat file as I described in
http://sources.redhat.com/ml/crossgcc/2005-10/msg00004.html
Maybe I should do that by default in the next crosstool,
since it seems to work so well.

See http://sources.redhat.com/ml/crossgcc/2005-01/msg00078.html
and http://www.linuxforums.org/forum/ptopic41994.html
for other people who ran into this, and fixed it manually a different way.

Let me know if that helps!
