Libgtop compile fail

[Gleef <dzol virtual-yellow com>]

When compiling libgtop off of CVS today, I got the following error:

gcc -DHAVE_CONFIG_H -I. -I. -I../.. -D_IN_LIBGTOP -D_GNU_SOURCE

I'm running a RedHat system with a 2.1.131 kernel and the
glibc-devel-2.0.106-0.981209 RPM from rawhide.  While this file appears in
the older glibc-devel-2.0.7-29 RPM, it is not in the newer version.  I
don't know if this is an oversight on the part of the glibc developers, or
if the file is being depreciated, but switching back to the linux/ip_fw.h
on my machine does not fix the problem.  It instead dies with:

Any ideas?  Or do I have to downgrade glibc for now?

Thank you very much,
