And to extend on this: this actually has weird effects. C99 bool will actually downgrade to "int" automatically when passed to functions as arguments (and vice versa). However gcc uses a different size in memory for this, which means that for doing call-by-value you can rely on this automatic conversion but if you do call-by-reference, then things will go boom in major ways.
