Comment (by anonymous):

 >gcc defines _MT if -mthreads is given on the command line (and that is
 the only difference).

 I'm not convinced that's the right thing to check - ideally what we want
 to know is "what configure options was libstdc++ compiled with?", and then
 set BOOST_HAS_THREADS uniformly based on that.

 Can someone please grep the headers for _GLIBCXX_HAS_GTHREADS: there
 should be a preprocessor based switch statement somewhere that selects
 which threading behaviour to use, and that's what we need to hook into.

 Thanks, John.
