John, I attached a diffent patch for the file to this mail which fixes the
problem. First of all, the platform in question is Tru64 (not HP-UX).

Next, when the file is included by the compiler, _GLIBCPP_HAVE_GTHR_DEFAULT
is _not_ defined. Therefore I changed the check to __osf__ && !_REENTRANT
to just unconditionally define _REENTRANT on Tru64.

If the patch is ok for you, please go ahead and commit it or just tell me
and I will commit it myself.
