Hm, then perhaps rangeobject.c shouldn't use it?

Its sole purpose is to support PyIntCheckExact. There is some code that relies that after PyIntCheckExact succeeds, it is safe to do PyIntAsLong. When I defined PyIntCheckExact to PyLongCheckExact, such code would break. Adding this "conservative" estimate allowed that code to work when the macro was true. As this occurs in some time-critical places, I did not want to waste time with computing a correct result. Regards, Martin
