-C option cure it... (that was hugs, wasn't it? I added -Fcpp_hugs to HUGSFLAGS, where cpp_hugs is script which wraps cpp. See the attachment.)
Haskell (with "syntactic sugar" rules) is quiet good itself. Cpp is mostly used for "#if" portability triggers, and it's good for the purpose. C-specific things is avoidable by various options. There is also gpp project. I didn't tried it, just read the announce. Maybe you could use it. http://auroux.free.fr/prog/gpp.html The another question is making the desugaring and layout parsing by the separate program(s). I think it would be good. Then, there could be possible to vary syntax by configuration of the preprocessor. There are lot of projects which propose it's own "sugars". Max.
#!/bin/bash cpp -P -traditional "$@"
