[ forwarded from http://bugs.debian.org/217075 ]

The warning is printed, if gcc is used, but not, if g++ is used.

I'm confused about the -Wformat behaviour in newer g++ 3.3 releases.
It works for plain C, but seems to be ignored for C++ (in some cases
at least).  Look at this:

egon@tuscan:~$ cat testik.cc
#include <stdio.h>

int main()
{
  printf("%d\n", 1, 1);
}
egon@tuscan:~$ g++-3.2 -Wformat testik.cc
testik.cc: In function `int main()':
testik.cc:5: warning: too many arguments for format
egon@tuscan:~$ g++-3.3 -Wformat testik.cc
egon@tuscan:~$
