What problem, exactly, are you solving here? In practice, if you tell
GDB to read an int it will read an int; if you tell it to read a byte
it will read a byte. It's only when accessing multi-word structures
that you get a problem. And in those cases it's sometimes possible to
teach the stub to handle it transparently.
