Only the bug tracker, which is here:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11953

Wolfgang Bangerth had no objection to the idea of a __GXX_PTHREADS
macro defined when -pthread is given, and Andrew Pinski targeted the
bug for GCC 3.4.1 - so it looks to me as though they're happy with it
and a fix will land before the next compiler release.

I've been meaning to prepare a patch myself (after digging through the
relevant files and figuring out how they work) but all my GCC time in
the last few days has been spent fixing libstdc++'s implementation of
the boost concept checks (which were also broken in 3.4.0).
