re PR c/19333 (C front end accepts arrays of incomplete types)
gcc/
PR c/19333
* c-decl.c (start_decl): Do not warn about arrays of elements with
an incomplete type here.
(grokdeclarator): Do it here by making a pedwarn an error.
* c-typeck.c (push_init_level): If there were previous errors with
the constructor type, do not warn about braces for initializers.
(process_init_element): Likewise for excess initializer elements.
