Prototypes for static functions that aren't used in between the prototype and
the actual static function definition are useless and could be cleaned up, I
think gcc itself has thousands of such useless prototypes.
It isn't hard to add a warning for this. Given:
static void foo (int);
#ifdef D
void bar (void)
{
foo (0);
}
#endif
static void foo (int x)
{
x++;
}
void baz (void)
{
foo (0);
}
we'd warn about the foo prototype (unless compiling with -DD).
