I think the churn rate in the gcc compiler specific #include headers will be low enough that a single combined file should be acceptable. Keeping all the gcc #defines together seems more readable to me. The trivial integration I did eliminated one duplicate #define as well as that hack for #include gcc_header(__GNUC__) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
