[issue43974] Define Py_BUILD_CORE_MODULE in extensions instead of setup.py and Modules/Setup

[Christian Heimes]

Christian Heimes <lists at cheimes.de> added the comment:

The proposal is related to Brett's ticket bpo-45548. I no longer think that we should define Py_BUILD_CORE_MODULE unconditionally. Instead I propose to move the defines into each C module. This avoids duplication of macros in setup.py and Modules/Setup.
