problem with parallel builds on AIX + NFS

[Richard Hedges]

I 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?

Thanks,
