 Actually, I was refering to the *-mt* flag which is hardcoded in
acc.jam i.e. there is no way to build single threaded libraries on
HP-UX. Command line is always: "aCC -mt +DD64". Please see acc.jam.

 From the link:
  [John] If so then BOOST_HAS_THREADS should get turned on
automatically when building in multithread-mode *only* in
boost/config/suffix.hpp.

 This fails to happen if I remove the hardcoded *-mt* flag and instead
instruct bjam to build both sinlge and multi threaded versions of the
libraries.
 Problems with bjam probably ? Seems like it's not passing *-mt* flag
to the compiler for multi-threaded build.
