Re: Changes to gcc 3.x to invoke an external cpp

Now I've got a clearer idea what you need and what you're doing I'm
not so against it, but it's not my call.

However, I would suggest the following would get a better review:

1) Choosing a good name for the switch

2) Factoring out the common specs into a sub-spec, just like cc1_options
   is.  Your original patch duplicates too many specs (e.g. compare
   the tradcpp part with what you did in gcc.c - all that's different is
   tradcpp), and specs are fragile enough as they are.

3) Full documentation.  I don't think your patch had any.
