Also:

extern Foo *variable;
Foo *variable;
{ Foo *variable; }
Foo *function(...);
Foo *function(...){...}
extern Foo *variable[];
Foo *variable[];
sizeof(Foo *);

All of which should probably be legal... unless pointers to structures
can vary in size, or you dereference !variable! or the return value of
!function!. The latter two can be checked out, but how about varying
size pointers to structures (eg, !struct {char c};! having the same align
restrictions as !char! and requiring a longer pointer than !int *!)?
