As a first approximation, you can start with the assumption that anything having to do with the C standard library is expected to be provided by the target system library. GCC does some transformations based on the standard semantics -- look for the so-called "built-ins" in the documentation. The options are sometime needed for the target library to profide some functionalities, so that means that it is close do impossible for GCC to know when a switch is selected by User L. but is not honored by the target library. -- Gaby
