But, do yourself a favor and, have it as an extension to allow
non-constant expressions to allow block scoped aggregates:

 void fn(int a)
 {
   int x[3] = { foo(), bar(), a }; /* not in C90 */

(You don't have to use it in the source code of the thing,
so it can be boostrapped by other C90 compilers without
the extension.)

Also, pin down the truncation behavior of / and % to match C99.
(Though, again, without relying on that in the C90 source
of the compiler.)

Define the behavior of a [0] array at the end of a struct,
so that the C90 struct hack is "blessed" in your implementation.
The C99 flexible array member cannot be used, after all.
You can have it so that [0] has the same semantics as C99 []
in that role.
