In my opinion this imposes an extra burden on the coder
and encourages the coder to implement functionality in
fewer functions -- the exact opposite of good style.  While
it's obvious that you should put function prototypes in the
header to expose the interface to a compilation unit, it
doesn't make sense to have to have the prototypes within
a compilation unit.  I mean, we are going to literally
write this in quite a few cases:

extern int function(void);
int function(void) {
}

Heck, I may as well just define a macro that doubles the
text and deposits a semi in between with an extern at
the beginning.

BTW, I should point out that these warnings are
apparently not being generated for c++ files, regardless
of the flag being provided to gcc for them.
