Compiler Returncode

[boriel]

This would be great! Thank you vey much. I welcome both functions.

I've just checked the compiler for this, and it *already* behaves as expected: Return error code 0 (OK) when there're only warnings. :?:
Can you check it on your computer? Or tell me exactly what kind of warning are you getting? Because here, warnings do not count for error codes (as expected).
