treat “implicit declaration of function foo” as error
Question
GCC gives a warning implicit declaration of function foo when you use foo() before its declaration. Is there any GCC flag that would make treat this warning as error and stop compilation? Sometime it would save you some debugging work...

-Werror will treat all warnings as errors. You can be more specific with -Werror-implicit-function-declaration
