Sure, I have no problem with it.

However, there was a good reason for the langhook which it looks like
Geoff might have broken.  We want CPP to accept an input and output
file on the command line like so:

cpp file.in file.out

(and similarly I guess for gcc -E).  cc1 used to be able to handle
this too, though I don't think cc1 matters too much.

If this has been broken (sorry I can't check just now) then it has to
be fixed.
