(Looks like you're using glibc-2.2.5, not glibc-2.3.3.  That should be ok, though.)

PATH_MAX is, I think, defined in linux/limits.h.
http://sources.redhat.com/ml/crossgcc/2005-01/msg00078.html mentions
someone having this problem and working around it by
fixing a missing symbolic link.
The symbolic link should have been created by these lines of crosstool.sh:

case "$KERNEL_VERSION.$KERNEL_PATCHLEVEL.x" in
2.2.x|2.4.x) make ARCH=$ARCH symlinks    include/linux/version.h

You may be able to work around this by using sanitized kernel headers.

Look at
gcc-3.3.6-glibc-2.3.2-hdrs-2.6.11.2.dat
See the line
LINUX_SANITIZED_HEADER_DIR=linux-libc-headers-2.6.11.2
?  Use that setting when running all.sh, and you
may find the problem vanishes.  Let us know what happens.
Good luck!
