problem with parallel makes on AIX + NFS

[Richard Hedges]

 am seeing the precise symptoms that were discussed previously:  see http://developers.sun.com/solaris/articles/parallel_make.html

The source target does exist and apparently is not detected effectively.  The problem is intermittent.

I didn't find any other detail on this, other than the version 3.79 or newer should fix the problem.  I am running 3.79.1 and have tried 3.80 as well.

Anything new on this or is anyone else experiencing problems with parallel builds on NFS?  Does anyone remember the details of this problem from the past?

Thanks,

- Richard
