 There is the GNU pth implementation and possibly HP provided it as an
 option.  However, the standard thread implementation was DCE threads.
 
 I haven't really had a chance to work on the thread implementation
 under hpux 11.  However, I have decided that probably we should use
 a multilib implementation as HP's "weak" support doesn't conform to
 the SYSV ABI with respect to undefined weak symbols.
