--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
FWIW, if printing a new note is a concern, perhaps simply enhancing the
existing warning to mention the appropriate format specifier for the type along
the following lines might be less nannying:

warning: format ‘%i’ expects argument of type ‘int’, but argument 2 has type
‘long long int’ which requires ’%lli’ [-Wformat=]
