            Bug ID: 65050
           Summary: Show the type for "array type has incomplete element
                    type" error
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c

In the following test case we have a few invalid decls.  It would be nice if
the C FE showed the incomplete element type.

typedef int A[];
struct S { int i; A a[5]; } s;

extern void foo (int p[2][]);
extern void bar (A p[2]);

void
foo (int p[2][])
{
}

void
bar (A p[2])
{
}

struct T;
struct T t[5];
struct U u[] = { { "abc" } };

typedef struct T TT;
TT tt[5];
