  I have the kernel-source for both the 2.4.18-3 and the 2.4.20-18.7,
which is what was required for all previous builds.

  Here's what I've come up with, and hopefully someone will understand
this better than I. ;)

Configure tests for sys_call_table to be exported.  It uses a short
program to compile which does a "#ifndef __ver_sys_call_table...throw
erro".  __ver_sys_call_table is defined for rh kernel 2.4.18-3, and also
a standard 2.4.20-xfs.  It is not defined for 2.4.20-18.7.  When this
happens, it doesn't set "EXPORTED_SYS_CALL_TABLE" in
src/config/afsconfig.h.  Then, cause of this, when it goes to compile
the libafs stuff, it fails on osi_module.c because it has this section:

#ifndef EXPORTED_SYS_CALL_TABLE
#include <linux/syscall.h>
#endif

Because EXPORTED_SYS_CALL_TABLE is not defined.  However, unlike older
redhat kernel versions, "linux/syscall.h" does not exist in 2.4.20-18.7.


Now...commenting that section out, so it doesn't attempt to include this
file seems to make it compile, but a) I'm not sure of the implications
of this, and b) if that's okay, then perhaps we need to just pull those
lines out?

Thanks,
  Tim(who is hoping this invokes more than a one line unhelpful
responce)
