Unexpected C code success

While running the following code in a file named test.c on Code::Blocks version 12.11:

#include <stdio.h>

int main()

{

display();

return 0;

}

void display()

{

printf("\nHi");

}

I am getting no error while on GCC 4.8.2, it says:

dec.c:9: warning: conflicting types for ‘display’

dec.c:5: note: previous implicit declaration of ‘display’ was here

Something is messed up in C code compilation as it is not affirming to C99 Standard.

So, what is the bug?

What is the expect result?

I am getting no such warning in Code::Blocks as shown by GCC for the above mentioned code.The compiler should show such warning on compilation.

So the problem is that you're not seeing the warning in the "Build log" or "Build messages" panels?

Keep in mind that C::B is not a compiler, but an IDE using a compiler available on your system!

Strange, everything’s right, two messages (though I use 13.12 with manually-installed MinGW 4.8.2).

Maybe, check for warning settings?
