 It has never been valid C to use an expression of aggregate type as part
 of an initializer, only as a the whole initializer, though the broken old
 implementation of compound literals may have allowed this.  I'll leave it
 up to Jakub to decide whether it makes any sense to allow this as another
 compatibility case of compound literals in gnu89 mode.
