The 64-bit linker doesn't mangle the dllexport'ed module init function (from PyMODINIT_FUNC) so it causes an exported name conflict.  We cannot just remove that name from export_symbols as the module may not have used PyMODINIT_FUNC on its init function.

The attached patch "fixes" the problem by suppressing the warning.

I personally would prefer the "pure" approach by assuming that the module initialization function would be required to be declared by PyMODINIT_FUNC and therefore the symbol would not need to be exported on the command line.

I think this is the same as #9709. Please just reopen if it isn't.

Distutils is now deprecated (see PEP 632) and all tagged issues are being closed. From now until removal, only release blocking issues will be considered for distutils.

If this issue does not relate to distutils, please remove the component and reopen it. If you believe it still requires a fix, most likely the issue should be re-reported at
