[Bug c/44257] New: typeof(*(struct undefined *)) fails to compile

[rusty at rustcorp dot com dot au]

struct foo; 
typeof(struct foo) *p; // This is fine.
typeof(*p) *p2; // foo.c:5: error: dereferencing pointer to incomplete type

This is important, because AFAICT the only way to declare a const pointer for a
given type is: "const typeof(*p) *" which doesn't work if p is a pointer to an
undefined struct :(
