The above are GDB's host types.

When representing target types (or stuff related to a protocol) GDB can 
either use a function like extract_unsigned_integer() or construct a 
type exactly describing the data using that (but be wary of byte order 
problems).

Trying to do something like:

struct { uint32_t i; ... }

can end up being non-portable (due to struct packing issues and the like).
