Sorry, Martin, but IMHO that is not correct.  I don't have my copy of
the Standard handy, but the last time I tried that (or something like
that) I found that the DG Avvion (Greenhills) C compiler either
complained or generated bad code (I forget which) if a function was
declared with ANSI prototypes and defined without them.

At that time I investigated and found that ANSI leaves that case
"undefined".
