It's not an error, so long as the argument types are what you would get
from the default argument promotions (as they are in this case).

However, it is not a good idea to mix new-style (prototype) and old-style
function syntax.  The proposed ANSI C provides rules for resolving the
collision of these two ways of doing business, but that's intended for
grandfathering in existing code, not to be used for new code.  New code
should consistently use prototype style for both declarations and
definitions.
