Here it is as patches. One problem with this method is that if the function implementation ever changes to _not_ return -1, then we get no warning that our macro and the function implementation have diverged in meaning. [1/2]: make error()'s constant return value more visible [2/2]: silence some -Wuninitialized false positives These would go on top of 1/3 from the original series to make -Wall -O3 clean (I'll repost the series as a whole when it is more obvious what we want to do). -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
