Hi, this patch fixes issue PR/59807 "mutex misses destructor if non-function call initialization is used". This issue just got reported for mingw-w64, as this is the only venture providing posix-threading enabled toolchains (C++11). Nevertheless this issue could happen for other native Windows toolchains, too. Therefore I adjusted the default mingw32-case, too. ChangeLog 2014-10-14 Kai Tietz <ktietz@redhat.com> PR libstdc++/59807 * config/os/mingw32/os_defines.h (_GTHREAD_USE_MUTEX_INIT_FUNC): Define to avoid leak. * config/os/mingw32-w64/os_defines.h: Likewise. I am just testing bootstrap for it, and if successful, I will commit. Thanks, Kai
