Going quite methodically through K& R ( as some of you can attest
to!), I have never seen a big diffference in declaring a function
within "main" or "ahead" of it. Now, (p119, K&R II), the discussion
states that "functions "whatever" " should be declared ahead of
main.
Is there a good reason for this?

In Standard C, functions cannot be declared "within" main(); these are
called nested functions and are implemented as an extension by some
compilers, but in general you should never use them. Therefore, the debate
is about whether to declare functions before or after main().

This would be true if you said "defined" rather than "declared". It's
perfectly legal to declare functions in main(), for example:

int main(void)
{
int foo(void);
...

and this does not create nested functions. It's not however
a common style.
