It's not that simple. Those warnings are the result of code flow analysis, and 
therefore may vary by compiler version or flags...

For missing.c, it seems really unimportant since most or all of that file is 
usually compiled out, and developers can learn to ignore warnings about it. I 
don't really care either way.

But the same problem affects other files too. For instance:

static void *ThreadFunc(void *data)
    /* ... Some stuff here ... */
    for (;;) {
        /* ... Stuff without break statement here ... */

    // To return NULL or not to return NULL ?
