 Olivier,
 
 >  John, could you please give it a try on HPUX 10 (removing -lpthread from

 The hpux 10.20 build was successful with the enclosed patch.  Possibly,
 the hpux test that you added should be after the DCE block but that
 doesn't matter for hpux 10.  I may try hpux 11 after I return from vacation.
 
 Thanks for your help,
 Dave
