I have no idea what the gcc developers recommend in order to detect multi-threading support or if this should be reported to the gcc developers as a bug. But it will certainly break many programs using Boost.
I've been meaning to get around to asking that on the gcc list. Unfortunately gcc.gnu.org seems to be down today.
It's up again. I posted the question to the gcc-help list (http://gcc.gnu.org/ml/gcc-help/2004-05/msg00099.html). Hopefully we will get an answer that enables us to make the BOOST_HAS_THREADS detection more reliable.
Maybe, you should ask the question on the main gcc list, or maybe even file a bug. After all, the situation is with earlier gcc version, it was possible to reliably detect if -pthread is specified and enable MT code in Boost. Now it's not possible, so as far as Boost is concerned, it's a regression in 3.4. And BTW, you're not the only one which sees the problem. It seems that Neal Becker has the same problem with the program_options library. - Volodya
