We are out of sync.  Let's back up, shall we?

What I was saying was that if you change `todigit' to accept an int as
an argument, *fmt will be promoted to an int when it is passed to
`todigit'.  This promotion is done by default if `todigit's
declaration is not visible to the compiler.

If you want an example of such function, look at `tolower'.

Okay?
