arrays and flexible arrays.
* c-typeck.c (really_start_incremental_init): Discriminate

like fixed-sized arrays.
* expr.c (store_constructor): Handle zero-length arrays and
flexible arrays correctly.
* doc/extend.texi: Update zero-length array notes.
* gcc.dg/20000926-1.c: Update expected warning messages.

array.
