You are right, see below.  I'm looking into how difficult it would be to
fix the --pedantic warnings too, but it does warn about some constructs
(like variadic CPP function macros) that we only use if they work.

address@hidden:~$ cat foo.c
void foo (void)
{
  return;
}

void bar (void)
{
  return foo ();
}

int main (void)
{
  bar ();
  return 0;
}
address@hidden:~$ gcc -o foo foo.c -Wreturn-type
address@hidden:~$
