Hi Jerry,

Thanks for the info.  I don't think we want to define
BOOST_HAS_PTHREADS unconditionally, because IIRC at least some
versions of HPUX's headers don't contain one or two of the functions
used by Boost.Threads

It's more effective to post a patch as an attachment, so there's no
ambiguity about how mailers have mangled it, and so it can be
automatically applied.
