Re: [boost] BOOST_HAS_PTHREADS, BOOST_HAS_SCHED_YIELD tests in config_test not strict enough

My point however was that this is no longer true, starting from g++ 4.1. _REENTRANT is now being set properly (and ignored by Boost.Config).

Is it?

Yes. See the link I posted previously. http://www.boost.org/development/tests/trunk/developer/output/Sandia-gcc-boo... This is Linux, _REENTRANT is not set, BOOST_HAS_THREADS is set - as far as I can see.
