Really?

Take the program below and notice that the constified prototype
introduces a warning.  If used from C++, that would be an error.

So this change is an API break.  That is not to say that it might
not be justified, but let's call it what it is.

static void foo (const char *s) { (void)s; }
static void bar (      char *s) { (void)s; }

int
main (int argc, char **argv)
{
  void (*f1) (char *) = foo;
  void (*f2) (char *) = bar;

  f1 ("");
  f2 ("");

  return 0;
}
