[New-bugs-announce] [issue28224] Compilation warnings on Windows: export 'PyInit_xx' specified multiple times

[STINNER Victor]

New submission from STINNER Victor:

I like when a compilation has no warning, because it helps to notice useful warnings and real bugs. The compilation of Python 3.5 on Windows emits the following warnings on buildbots:

xxmodule.obj : warning LNK4197: export 'PyInit_xx' specified multiple times; using first specification
xxmodule.obj : warning LNK4197: export 'PyInit_xx' specified multiple times; using first specification
xxmodule.obj : warning LNK4197: export 'PyInit_xx' specified multiple times; using first specification
