  | int main(void) { 	return foo(); }

[I squashed those up to make the mail take less vertical space ...]

Typically I want neither of those - I want foo() to be global, so it gets 
entered in the global symtab for nm -g and remains after cc -x
but I am not expecting it to be called from anywhere but this one
location (and certainly not outside this file.)

My typical "solution" is simply to shove

	int foo(void);

immediately before the "int foo(void) {" line,
which silences the warning, but is otherwise just a waste of space.
