Is the following legal?

I checked ANSI X3.159-1989, and can't find anything that forbids it.


   int dop[][] = {{1,2,3}, {4,5,6}};

I was expecting a constraint saying something like 

      ... for an array of type T, T must be a fully specified
      type.

But it's not stated that obviously if it is a constraint.      

GCC doesn't accept it, and issues the diagnostic errors

sw131.c: In function `empty_aggregate_bounds_error':
sw131.c:3: elements of array `dop' have incomplete type
sw131.c:3: array size missing in `dop'
sw131.c:3: storage size of `dop' isn't known

The MetroWerks C compiler does accept this syntax.
