What about just changing the cpp section to comply with ANSI C input while
producing old K&R C output? The ACK compiler could then be extended to handle
a few extra features (eg void* & const ...)

The hacky changes to the language are mostly in the #defines
and how they behave. Modifying just cpp should cover this.

I say hacky because people have a habit of using old K&R features
with defines that are not formally specified eg
        #SYMB           instead of "SYMB"
        A ## B          instead of A/**/B
(Read an ansi C manual)

Umm this should not be taken as an offer to do this just a suggestion
for a 'cheap' solution.
