Typedefs in C are just aliases, so given `typedef int foo;` one can freely use `int`s and `foo`s interchangeably, i.e. no checking by the compiler.

That said, one could use actual wrapper structs around the various types.

A static analysis framework could treat certain typedefs specially since it's parsing the C code anyway.

Great idea! Too bad openssl uses #define instead

There's also sparse[0]'s address space annotation, which Linux uses for annotating data from userspace.
