busybox-1.5.0 miscutils/taskset.c compile errors

[Ulf Samuelsson]

It seems that there is some undefined defines's in the "taskset.c"

CPU_ISSET
CPU_SETSIZE
CPU_ZERO
CPU_SET

They are supposed to be set in "sched.h", and they are present in 

/usr/include/sched.h 

on my OpenSuse PC, but they are not present in linux-2.6.20.4 tarball

I could not find them in the toolchain includes...

Any clues?

Best Regards
