My confusion here is how can you "canonicalize" types that are different
(meaning have different names) without messing up debug information.
If you have:

	Foo xyz;

and you display xyz in the debugger, it needs to say it's type "Foo", not
some similar-but-differently-named type.

Or maybe this is C++-specific and isn't relevant in C, so I'm not going to
understand it.
