No, I just messed up. Sorry. I had misread the gnulib manual and thought
that it magically provided drop-in replacements of nprocs and
nprocs_conf. In fact, as I think Ben already knew, its nproc module
provides similar functionality through its function called
"num_processors".

I have updated nprocs.cc. It no longer provides `nprocs' and
`nprocs_conf', as we can't actually call native system routines of these
names across different platforms. Instead it provides `nproc', which
like the newish coreutils program of the same name, uses gnulib's
`num_processors' function. The new function takes an optional argument
to access the functionality available in the underlying gnulib routine.

An hg changeset is attached to this email. I don't know if that makes it
through the mailing list, so I'll attach it to the patch queue item at:
    http://savannah.gnu.org/patch/index.php?7504
as well.

If Ben could see if this works in Mac OS that would be great. I only
have access to GNU/Linux here.

Iain.
