[cfe-dev] -Wimplicit-function-declaration doesn't work?

[Alexei Svitkine]

I'm trying to get the warning output of the code:

int main(void)
{
	strcmp("abc","def");
	return 0;
}

However, running "clang -Wimplicit-function-declaration" doesn't seem
to produce any output.

Am I doing something wrong?
