[Toybox] Any language lawyers here?

[Rob Landley]

I'm arguing with C:

If I do the equivalent of:

extern int blah[] = {0,1,2,3,4};

int main(int argc, char *argv[])
{
  printf("sizeof(blah)=%d\n", (int)sizeof(blah));
  return 0;
}

I get:

temp.c:3: warning: ‘blah’ initialized and declared ‘extern’

But if I just have extern into blah[] without the initialization, I get:

temp.c: In function ‘main’:
temp.c:7: error: invalid application of ‘sizeof’ to incomplete type ‘int[]’

The second of which at least makes sense.  The first is just stupid. I
want to have one common instance of the kill signal list, _and_ I want
various things to be aware how big the size of the thing is, and the
compiler's determined to give me a warning for doing something which I
_believe_ the language allows...

Is there some kind of "yes I know what I'm doing, shut up gcc"
annotation I can put on that line without having to hardwire in a
constant and maintain it by hand?  (I want to make the extern a #define
which lib/lib.c can set to semicolon or something, and everybody else
can have as "extern"...)
