Re: [boost] boost/config/suffix.hpp: spurious BOOST_HAS_THREADS withg++ 3.4

It looks as though _GLIBCXX_HAVE_GTHR_DEFAULT is defined by the std lib when
it's in thread safe mode, so I'm leaning towards adding:

#ifdef __GLIBCXX__ // gcc 3.4 and greater:
#ifdef _GLIBCXX_HAVE_GTHR_DEFAULT
#define BOOST_HAS_THREADS
#else
#define BOOST_DISABLE_THREADS
#endif
#endif

To our libstdcpp3.hpp config file, which I think will take care of it,
albeit not in a way that everyone will appreciate (it will force threading
on whenever the std lib is also thread safe).

Thoughts?

John.
