klibc - Aug 2007 - Klibc 1.5.4 build issues

I'm working with klibc as a part of trying to port LTSP version 5 into 
Red Hat 4 and 5. Red Hat does not  appear to have a very good set of 
utilities for playing in early userspace like LTSP's boot process 
requires so I thought I would try klibc since I could then base my port 
more closely on the Ubuntu/Debian work. Problem is I can't seem to get 
klibc to build against the RHEL 4 kernel (2.6.9 with a boatload of patches).

Here is the result of the make command:
[root@****** klibc-1.5.4]# make

Thanks in advance for any help you can offer.

Yes, that's much too old.

You might be able to build against a newer set of kernel headers and 
still use the resulting binaries, but I can't guarantee it.

This means you're using the Red Hat poisoned headers.  They're 
definitely not going to work.
