--- Comment #9 from Samuel Bronson <naesten at gmail dot com> ---
Wouldn't the case where a given custom printf-like function does more than just
print the formatted text be better solved by adding a new __attribute__ to
disable this warning for such a function?  (Assuming anyone actually wants
these warnings ever ...)

Then, you could still have warnings for code like 'printf();' that does
nothing, while avoiding them for your 'custom_printf(foo, "");' that does do
something.
