[issue17870] Python does not provide PyLong_FromIntMax_t() or PyLong_FromUintMax_t() function

[STINNER Victor]

STINNER Victor added the comment:

Oh, the sqlite3 module has an interesting function:

PyObject *
_pysqlite_long_from_int64(sqlite_int64 value)
{
#ifdef HAVE_LONG_LONG
# if SIZEOF_LONG_LONG < 8
    if (value > PY_LLONG_MAX || value < PY_LLONG_MIN) {
        return _PyLong_FromByteArray(&value, sizeof(value),
                                     IS_LITTLE_ENDIAN, 1 /* signed */);
    }
# endif
# if SIZEOF_LONG < SIZEOF_LONG_LONG
    if (value > LONG_MAX || value < LONG_MIN)
        return PyLong_FromLongLong(value);
# endif
#else
# if SIZEOF_LONG < 8
    if (value > LONG_MAX || value < LONG_MIN) {
        return _PyLong_FromByteArray(&value, sizeof(value),
                                     IS_LITTLE_ENDIAN, 1 /* signed */);
    }
# endif
#endif
    return PyLong_FromLong(value);
}

If PyLong_FromIntMax_t() is implemented, this function may be simply removed 
(and replaced with PyLong_FromIntMax_t).
