To avoid exactly this problem, we added a warning to gcc (about
version 1.37 or so) which warned if a globally visible function was
declared without a prototype. This made it into gcc 2.0 as
-Wmissing-prototypes. This reduces the problem to ensuring that the
prototype appears in only one header file.
