Multiple issues making the build fail: * _InterlockedExchange8 is missing in mingw-w64, filed in mingw-w64/mingw-w64#118 * cffi_atomic_store_ssize is missing casts, leading to errors * __ldar8/__ldar64 are not supported in gcc/clang Just use the builtin compiler intrinsics everywhere for GCC/Clang when targeting Windows. Same as is already done in misc_thread_posix.h See python-cffi#159

Pending #137 to make the windows CI runs faster, maybe we should add a mingw CI run for a single python version. On the other hand, what is the priority for this compiler? I would expect many mingw users can |

There is no priority for me at least, I patched it downstream in MSYS2 already. I just had the patch anyway, and saw the issue, so proposed it. There are no compatible binary wheels, so pip always builds from source (and as a result it's not easy/error prone) |

Thanks @lazka |
