43 | // This is a hack around not having either pre-compiled headers or | |

46 | // implementation optimizes the headers for the most commonly-used | |

71 | // In those parts of the standard C++ library that use a mutex instead |

75 | // gthr-single.h which is a correct way to express no threads support | |
76 | // in gcc. Support for the undocumented _NOTHREADS has been removed. | |
