+- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
+ variable argument list. `Py_VA_COPY` is equivalent to C99
+ `va_copy`, but available on all python platforms.
+
- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
"step = -step" when reversing a slice.
