possible bug in parse.y?

I don't have a repro on this, but I saw it while debugging some of my  
code and thought it was wrong.

If the patch below isn't correct, then it should probably be "(void)"  
instead of "id =" to show that we really don't want the result. (or  
it might be that id should be id2). I dunno, but someone does.

in rb_id2name:
