Seems to be a regression, gcc 4.5 says
ice2.c:2:12: error: array size missing in ‘a’
ice2.c:2:8: error: expected specifier-qualifier-list at end of input
and doesn't ICE.

And even better:
typedef int A[];
struct { int i; A a; } a;
Clang accepts the code, we say (released compiler):
ice2.c:2:19: error: array size missing in âaâ
struct { int i; A a; } a;
^
and ICE with checking enabled since 4.6.

Yeah, initially I had the invalid testcase as in #c0, only then I discovered
that we ICE even on a valid testcase with a typedef. Which means there are two
issues: a) we ICE, b) we don't accept a code where a flexible array member is a
typedef. I'm adjusting the keywords now.
