Re: The importance of prototypes

Thanks for the help guys,

Browsing around in gnu.gcc.bug I see that in gcc if no prototype is
given, the function passes all arguments as ints (no matter the local
data type or the function declarations desired data type). I am
wondering if this is the way the C standard designated it, or if gcc is
taking a liberty here.

This seems silly as this is just memory which I would expect would be
directly copied to the stack if no prototype is given to say otherwise,
not casted behind the scenes.
