Compiler level 2 warnings

[Alessio]

Hi, I was wonder why this code

Code Select Expand

#include <stdio.h>

int main(void) {

int i;

i , 2;

return 0;
}

do not generate a warning until I set compiler level warnings to 2.
I'm just damn curious!
I've spent a day to found a bug in my code...from now I'll set compiler level warnings to 2 on every project.

Thank you.

It's an example of the comma operator, which is perfectly valid. Maybe "Expression with no effect removed" should be at level 1, but I'm not completely sure it's a good thing.
