Re: Problems with pthread detection under HPUX 11.0 (ITS#14)

Try the attached patch. I've tested it under the HPUX 11 boxes I have. A quick
run on one of my remaining 10.20 boxes shows that this bit of code never gets
excercised.

That isnt so much of a hardship as 10.20 had horribly broken DCE threads
anyways. The only situation I can think of in which this patch might get
confused/fail to work is with HPUX 10.30 machines. 10.30 had usable threads,
but since we got rid of our 10.30 machines some time ago, I cant work up an
appropriate test.

Again, I dont really forsee this to be a big issue. 10.30 wasnt in general
release - it was only available if customers complained loudly enough. HP
strongly encourages everyone to go straight to 11.00 these days.
