But do we need the fallback? Further below we are also unconditionally using preprocessor-defines like __INT_MAX__ and __LONG_MAX__. So I guess we can drop the proposed #ifdef. > Please just let me know if you want me to modify your patch accordingly. > I'm still continuing the tests. Feel free to modify the patch. Thanks! Thomas
