00087  * type is usually detected automatically through preprocessor macros,
00088  * but the automatic detection cannot know whether the code needs to
00089  * and can be linked with an implementation of division for that type.
00090  * By default division is assumed to be usable if the type is present.
00091  * Uncomment this option to prevent the use of double-width division.
00092  *
00093  * Note that division for the native integer type is always required.
