r-devel fails tests for parallel

On Thu, May 17, 2012 at 9:04 AM, Prof Brian Ripley
Seems your ancient OS (that compiler has a 6-year-old copyright date) has a
broken implementation of affinity with CPU_ZERO but not CPU_COUNT.

I've added some checks which should catch this.
Thanks a lot.

And I apologize for mixing up the red hat version.  I am using EL 5.4.

FInally, while GCC 4.2 is pretty old, it is still the newest release
under GPL 2.  And (more importantly to me), it is the system compiler
on our cluster.

Hmm, it says .el5: RHEL5 is ancient but RHEL4 is pre-historic!
