[PyQt] PyQt5 5.7.1 Bug: debug build on Windows broken

[Mathias Born]

Phil,

It looks like the change to the limited Python API broke the
debug build on Windows.
I get error messages like:

c:\cpp\python\python-3.6.0\include\object.h(65): fatal error C1189: #error:
Py_LIMITED_API is incompatible with Py_DEBUG, Py_TRACE_REFS, and
Py_REF_DEBUG

That's a severe limitation for every program embedding Python and PyQt5,
because the debug build of such a program must link to the debug version of
Python
and PyQt5.

Best Regards,
Mathias
