Ok Thanks Amy.
Language.C was not working yesterday and is working now today.
Maybe I mistyped something

Now I find that I am directed to do at page
http://trac.sivity.net/language_c/wiki/GettingStarted

module Main where
import Language.C
import Language.C.System.GCC   -- preprocessor used
main = parseMyFile "test.c" >>= printMyAST

Whats with the double import?
Does not the contents of Language.C get imported when that is imported?

[Note this is not so much a question specific to Language.C as to the
general nature of module namespace structuring in Haskell]
