This is a long-standing and well-known bug in
/usr/src/linux/kernel/sched.c It has been in all of the Fedora kernel
source packages and never been fixed, although the fix is perfectly
simple.
This bug did impede an i686 rebuild, but not an athlon rebuild.
In that file, there is one relevant function definition inside
an #ifdef. It should be outside. Move it down one line, thusly:
$ diff -c sched.cSTD sched.c
*** sched.cSTD Wed Jan 7 12:49:58 2004
--- sched.c Mon Jan 19 13:49:07 2004
