I think this is a problem one other user also experienced: The system
call IPC library (called ``emulation library'' for hysterical reasons)
in linux/arch/l4-i386/emulib/ has been linked to a wrong virtual
address because the magic in this directory's Makefile failed.  One
possible reason is that you don't have a `cpp' in your $PATH.

Does it help to replace "cpp" with "gcc -E" in this Makefile?
