* 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/20080820.c, gcc.dg/anon-struct-1.c: Update expected
diagnostics and type sizes.
