Hello.

I want to allow a configure script to be told the number of CPUs

want to have something AC_DEFINE CPUS to be an integer read whilst
configuring the program.
I have no idea if this will work for your software, but:
Wouldn't it be better to detect the number of processors at runtime? See
(for glibc on Linux):
info libc sysconf constant
and search for the constant "_SC_NPROCESSORS_ONLN".
