[Cython] Pyrex and const (Re: constify Cython output all over the place (newbie approach))

There's something I've been meaning to ask people
about. Until I find a way of handling const properly,
I'm considering having Pyrex put this at the top of
its generated files:

   #define const

so that all Pyrex-generated code will be a totally
const-free zone.

But I don't want to do this if there's a chance
it could break something. Can anyone think of any
problems it could cause?
