After installing python3.4.0b2.amd64 and rebuild modules, most of them stoped works. List of modules is [psutil, ujson]. Exception occurs on importing module: import error: dynamic module does not define init function PyInit_<module_name> and I found solution (workaround) - need change declaration of init function: Line: PyObject *PyInit_<module_name>(void) was changed to: PyMODINIT_FUNC PyInit_<module_name>(void) and module works fine after rebuild. All works fine with 3.4.0b1 and all alpha versions. I have windows8.1 x64.

Thanks for the report! -- That's due to the commit in #9709. PyMODINIT_FUNC is more than ten years old, so I hoped people would be using by now. On the other hand that's serious breakage. Martin, would you have time to make a call on whether to revert the change?

Ping. The blocker seems to have passed beta3. :)

I think the change should be reverted, and the original issue closed as "won't fix". Alternatively, to fix the original issue, the specific linker warning could be suppressed.

Thanks, that seems to be the best course of action. Fixed in 69827c2ab9d0.

Issue #16779 has a patch that suppresses the warning for 64-bit builds that would also "fix" #9709.
