Looks like we might need to do some work on the platform config for hpux. 
Basically, if BOOST_HAS_THREADS is set date-time 'assumes' the platform has
the _r functions available.  Looking at the config for hpux it looks like it
doesn't really setup BOOST_HAD_THREADS correctly.  Looks like maybe the
config/platform/hpux.hpp should include the posix_features.hpp file like
solarias does.  So you might try adding 

#include <boost/config/posix_features.hpp>

to the end of the file above.  I'm cc'ing John Maddock since he's the config
guru -- John any thoughts?
