<div>
<pre>Compiling
int main() { return f(); }
with -Weverything triggers both -Wimplicit-function-declaration and
-Wstrict-prototypes:
example.c:1:21: warning: implicit declaration of function 'f' is invalid in
C99 [-Wimplicit-function-declaration]
int main() { return f(); }
^
example.c:1:21: warning: this function declaration is not a prototype
[-Wstrict-prototypes]
2 warnings generated.
This seems redundant – implicit function declarations will never be prototypes.</pre>
