Warning when duplicate instance variables

Hi,

It's possible by mistake to create a class with duplicate instance
variable, the following patch checks and warms the user. I plan to
do the same but for duplicate methods defined on a class.

Is it done also when the first name is in the superclass?  I'm not sure
I'd like that (ANSI says it must not be an error BTW).

Nice, you can do that in the parser too.  Much more useful, actually!

It's done for super and sub classes. I understand but this is just a
warning here, and I've made it because
the developer - here me :) - can loose a "lot" of time because of such
kind of simple bug.
