As far as I can tell, your patch to make-prime-list.c works.  I'm
currently doing a build with a hack to try fix the threads issue.

The 'j' printf modifier is not supported on HP-UX at least through
to 11.11.  GCC doesn't parse printf format strings to detect unsupported
features.  The string "%ju" outputs "ju".  As a result, the argument
processing messes up.  This is what causes the runtime crash.

So, the other instances where %j is used need examination.

Don't know about '*'.

Thanks,
Dave
