This patch adds the new thread model `mcf`, which implements mutexes and condition variables with the mcfgthread library. Source code for mcfgthread is available at <https://github.com/lhmouse/mcfgthread>. config/ChangeLog: * gthr.m4 (GCC_AC_THREAD_HEADER): Add new case for `mcf` thread model gcc/ChangeLog: * config/i386/mingw-mcfgthread.h: New file * config/i386/mingw32.h: Add builtin macro and default libraries for mcfgthread when thread model is `mcf` * config.gcc: Include 'i386/mingw-mcfgthread.h' when thread model is `mcf` * configure.ac: Recognize `mcf` as a valid thread model * config.in: Regenerate * configure: Regenerate libatomic/ChangeLog: * configure.tgt: Add new case for `mcf` thread model libgcc/ChangeLog: * config.host: Add new cases for `mcf` thread model * config/i386/gthr-mcf.h: New file * config/i386/t-mingw-mcfgthread: New file * config/i386/t-slibgcc-cygming: Add mcfgthread for libgcc DLL * configure: Regenerate libstdc++-v3/ChangeLog: * libsupc++/atexit_thread.cc (__cxa_thread_atexit): Use implementation from mcfgthread if available * libsupc++/guard.cc (__cxa_guard_acquire, __cxa_guard_release, __cxa_guard_abort): Use implementations from mcfgthread if available * configure: Regenerate
