I think:

array must be initialized with brace-enclosed initializer

would be better. I also suspect that there are cases you will miss, like:

int b[2] = x->a;

That's neither a VAR_DECL or a PARM_DECL. What happens if you issue the error whenever INIT is not a CONSTRUCTOR? (The representation for a brace-enclosed initializer?)
