I think it does: it has the once_flag() initialization that fails to
compile. This is from libstdc++-v3/include/std/mutex, controlled by
#if defined(_GLIBCXX_HAS_GTHREADS) && defined(_GLIBCXX_USE_C99_STDINT_TR1)
How are those macros defined in <target>/libstdc++-v3/config.h before
and after my patches?
That's why I regularly ask for -g3 -save-temps output; this way, the
macro definitions are kept in the preprocessed output and you can see
this for yourself.
