I tried to build gcc from the latest snapshot (gcc-4.3-20071005),

[!__GTHREAD_HAS_COND] Fall back to the old code, which deadlocks.

But libstdc++-v3\libsupc++\guard.cc uses the class __guard from
libstdc++-v3\include\ext\concurrence.h which depends on the symbol
__GTHREAD_HAS_COND and is undefined now.
Hmm? __guard is a typedef in cxxabi-tweaks.h and doesn't depend on
__GTHREAD_HAS_COND.
