Some PyInt_ functions exist in intobject.h, which you need to include

Depends on what you want to test. If anything that has nb_int available
is sufficient, check for presence of nb_int. If you only want to test
for int-or-long, use intobject.h, and write
if (PyInt_Check(o) || PyLong_Check(o))
If you don't want to use intobject.h, write
#define PyInt_Check(x) PyLong_Check(x)
at the top, then use the same if block.
