// C basically never requires an explicit forward declaration, all uses of
// structs are elaborated.
struct AnotherStruct* s = 0;  // No diagnostic expected.
struct YetAnotherStruct* ReturnAStruct();  // No diagnostic expected.
typedef struct TypedeffedStruct TypedeffedStruct;  // No diagnostic expected.

// However, if an elaborated struct declaration appears in the parameter list
// of a function declaration, Clang will throw a warning that the declaration
// won't be visible outside the function. We avoid that warning by suggesting
// that an explicit forward declaration would be better.

// If an existing forward-declaration is available, make sure we don't suggest
// adding it twice (see issue #682).
