* c-decl.c (grokfield): Allow typedefs for anonymous structs and

	unions by default if those structs and unions have no tags.  Do
	not condition anonymous struct and unions handling on flag_iso.
	Allow anonymous structs and unions for C1X.
	(finish_struct): Do not diagnose lack of named fields when
	anonymous structs and unions present for C1X.  Accept flexible
	array members in structure with anonymous structs or unions but no
	directly named fields.
	* doc/extend.texi (Unnamed Fields): Update.

testsuite:
	* gcc.dg/c1x-anon-struct-1.c, gcc.dg/c1x-anon-struct-2.c,
	gcc.dg/c90-anon-struct-1.c, gcc.dg/c99-anon-struct-1.c: New tests.
	* gcc.dg/20080820.c, gcc.dg/anon-struct-1.c: Update expected
	diagnostics and type sizes.
