This is sort of a drag as the whole point was to have access to the
underlying gnulib module which should be portable.
I'm not familiar with this either, but I infer that we should be using the 
gnulib nproc module.

I assume there is some problem with that?
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

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:
as well.

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

Works for me!

I made a few minor mods and checked in the changeset.  Hopefully it will
also work on mingw...


Yes, it compiles on MinGW again.

octave.exe:1> nproc
ans =  2

And the answer is correct for my dual-core CPU.
