When compiling cpython with specifying NSMALLPOSINTS and NSMALLNEGINTS macros as zero to skip making small_ints[] array, like following command, process couldn't finish.

$ ./configure CPPFLAGS='-DNSMALLPOSINTS=0 -DNSMALLNEGINTS=0'
$ make

The reason looks a problem that PyLong_FromLong(0) returns irregular int object: Py_SIZE(zero_int) must be 0, but it becomes 1.

maybe this problem never appears in actual cases, but in "longobject.c", it still looks supported to compile without small_ints[].
I don't know it should be fixed or not. but, as a result, I could compile cpython after addition of one line like attached patch.
Could you confirm this point?

Thanks.
