* c-decl.c (grokdeclarator): Mark [*] arrays in field declarators
as having variable size. Do not give an error for unnamed

with [*] declarators and mark them as variable size.
* c-parser.c (c_parser_sizeof_expression): Do not give an error
for sizeof applied to [*] type names.
testsuite:

* vla-6.c: Likewise. Expect warning not error for [*] lexically
inside function prototype but not part of parameter declarator.
