 State-Changed-Why:
     This is not a bug in GCC, but in your C library.  GCC
     (if given the -Wformat or -Wall option) does not object
     to your formats.  If your C library does not handle them
     correctly, this is a bug in it; GCC does not provide a C
     library.
     
     I noticed that the declarations in your file - presumably
     from your system headers - declared printf and scanf
     to return void.  The ISO C standard says they return int.
     This suggests that your C library does not follow the
     C standard very well.  You could ask your vendor about
     the availability of a more recent version of your C
     library.
