# Bug report
### Bug description:
While fixing pywin32 to let CI builds work in Python 3.13, the build process complained of not being able to find `_PyLong_NumBits`. All other Python versions in the CI built successfully.
```c
BOOL PyCom_VariantFromPyObject(PyObject *obj, VARIANT *var)
{
// ...
if (PyLong_Check(obj)) {
int sign = _PyLong_Sign(obj);
size_t nbits = _PyLong_NumBits(obj);
if (nbits == (size_t)-1 && PyErr_Occurred())
return FALSE;
// ...
}
```
The function still exists in `main`, apparently inaccessible via the public C API since 3.13. What's the recommended replacement?
### CPython versions tested on:
3.8, 3.9, 3.10, 3.11, 3.12, 3.13
### Operating systems tested on:
Windows
