* c-typeck.c (really_start_incremental_init): Discriminate between zero-length arrays and flexible arrays. (push_init_level): Detect zero-length arrays and handle them 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. * gcc.dg/array-2.c: Likewise, and test for warnings too. * gcc.dg/array-4.c: Likewise, and don't verify the zero-length array.
