Py_LIMITED_API is not set or set to the value between 0x03050400
and 0x03060000 (not including) or 0x03060100 or higher.

PyArg_VaParse() and PyArg_VaParseTupleAndKeywords() were not available in
limited API.  PyArg_ValidateKeywordArguments(), PyArg_UnpackTuple() and
Py_BuildValue() were not available in limited API of version < 3.3 when
PY_SSIZE_T_CLEAN is defined.

Warnings could be emitted at compile time.

The “readline” module already has a workaround using setlocale(LC_CTYPE,

the locale string and cause the test framework to complain.

and Mercurial helpfully merged the two in a kind of nonsense way.)
