Does CG complain about
   char buf[100];
   sprintf (buf, "%25s", "richard" );

How about
   char buf[100];
   char *r = new char[26];
   strcpy (r, "richard");
   sprintf (buf, "%25s", r);

That should stop the complaining.

You could even do this
   char buf[100];
#ifdef _CG_
   char *r = new char[26];
#else
   char *r = new char[8];
#endif
   strcpy (r, "richard");
   sprintf (buf, "%25s", r);

Just make sure you aren't bypassing an actual error...
