I think so, because config.h is generated from config.h.in and ends up looking like: #define HAVE_SOME_FUNCTION 1 src/globals.h is controlled directly by us, and ends up looking like: #ifdef HAVE_SOME_FUNCTION #include <header_for_some_function.h> #endif If we add all the defines that may be missing that same ifdef section, and make sure that all code includes globals.h, then all the code will have the "HAVE_SOME_FUNCTION" defines and the appropriate header files and definitions included. > Either way having a single header for the various flags that might not > be present in the system headers sounds like a good plan. *nod* Cheers, Dave. -- Dave Chinner david@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
