The patch attached enables -Wsign-compare and -Wunreachable-code if supported by the compiler. AFAICT, mixed sign comparison warning is automatically enabled by Microsoft's compiler, and is usually a good thing. It does add some warnings though. As for unreachable code, it's also usually a good thing, since it can be a source of bugs. Note that it's not enabled in debug mode, since in debug mode the code paths aren't the same. |

The patch adds a a lot of new warnings. Would it be possible to fix them before applying the patch? |

Enabling the warnings may be a good incitation for other people to fix them ;) |

GCC >=4.5.0 (released on 2010-04-14) silently accepts and ignores -Wunreachable-code option. I think that build system of Python should not pass unused options to compiler. |

See Issue #24324 which modifies configure to not use -Wunreachable-code with gcc for the reasons stated there and by Arfrever above. |
