Explicitly casting the return type to char * would be a grave
programming mistake, and the coder would violate his own rules.

Even in the example below you will get a warning. Explicitly casting
path2 to char * is about as silly as the above.

char *dirname (const char *path)
{
     char *path2 = path;
     char *slash = strrchr (path2, '/');
     if (slash)
         *slash = '\0';
     return path2;
}
