    Compile warning fixes.
    
      Include header with prototypes for signals.c, and change prototypes and
    definitions to match. This should not have any side effects as function
    arguments are ignored.
      Ansify some functions with K&R definitions.
      printhex.c:fprintfhex() could be changed to a "sane" implementation, but
    only change was "ansification".
