(d) For those differences that cannot be eliminated implementing (in Haskell) a portable preprocessor that can ship as part of every Haskell environment?
I think this is ultimately going to be the most viable solution. Let's write a simple 'hspp' (in Haskell?) that is backward compatible with 'cpp -traditional' (although we might also design a newer nicer syntax too), and distribute it with every compiler. It can't be too difficult, surely? Half of the cpp parsing/selection code is already available within hmake. I would take on the project myself, if I had time.
I agree that this should be possible with the hmake code. FWIW, I have, in fact, already teased that functionality out (to a small degree) and made it available in my work-in-progress HMake API.
Will such a preprocessor work on source code like cpp does or on a syntax tree? The latter would be better, IMO; the former would probably have little or no advantage over cpp. I
