#define _CFFI_ /* We try to define Py_LIMITED_API before including Python.h. Mess: we can only define it if Py_DEBUG, Py_TRACE_REFS and Py_REF_DEBUG are not defined. This is a best-effort approximation: we can learn about Py_DEBUG from pyconfig.h, but it is unclear if the same works for the other two macros. Py_DEBUG implies them, but not the other way around. Issue #350 is still open: on Windows, the code here causes it to link with PYTHON36.DLL (for example) instead of PYTHON3.DLL. A fix was attempted in 164e526a5515 and 14ce6985e1c3, but reverted: virtualenv does not make PYTHON3.DLL available, and so the "correctly" compiled version would not run inside a virtualenv. We will re-apply the fix after virtualenv has been fixed for some time. For explanation, see issue #355. For a workaround if you want PYTHON3.DLL and don't worry about virtualenv, see issue #350.
