[Bug c++/13123] New: -Wformat doesn't detect printf() format mismatches in C++ code

["jthorn at aei dot mpg dot de" <gcc-bugzilla at gcc dot gnu dot org>]

The printf() format mismatch in the following program is warned about when
compiling with gcc -Wformat, but not when compiling with g++ -Wformat:

#include <stdio.h>

void foo()
{
int i;
printf("%g\n", i);
}

I will attach the output of    gcc -v -save-temps -Wformat -c
and    g++ -v -save-temps -Wformat -c    on this file.
