  You have to use

  int foo(int);

  of course, as an (ANSI) prototype for the rest of the code (and that's
how it ought to be done with the current coding style [with the
appropriate __P() around it]).

  But as Chris pointed out, this is very error-prone, specifically for
types like xyz_t (that might even expand to different base types on
different architectures ;-)
