Then I overinterpreted your messages, sorry.

Prototypes are "Schall und Rauch" without implementation.  By "in the same
file" I imply that those functions somehow have a "content", because
contentless things can't be anywhere, and in fact are no things at all.
The only reasonable definition for content of a function is it's
implementation, ergo I was talking exactly about that implementation ;)
Btw. that "in the same file" does _not_ only hold for source files.  In
fact those "two" functions must not even be in the same executable (if
they come from libs or the exe itself is irrelevant), if their names are
globally visible (or at least visible at two different points (in time or
space)), and they are not weak and no other means exist to somehow
prioritize one implementation over the other, and they haven't the
exact same semantic so that any conflicts don't matter.  From that
follows, that my notation had nothing to do with prototypes but was
language independant metasyntantic sugar to make my mail understandable (I
should have left out the ";"'s)   ;-))

You guessed it ;)

I fully support that.

Dito. (where appropriate ;) )
