Thanks for the pointer!

To clarify, when you're talking about mangling the EH names, do you mean the names of the typeinfo structures themselves (OBJC_EHTYPE_* in my implementation), or the typeinfo name strings inside those structures? The latter should be equivalent to structs for us too, i.e. `@catch (I *)` and `catch (struct I *)` would produce the same name in the generated type info.
