C Preprocessor

6 Dec 2007


      Is it already a known problem that the preprocessor cannot cope with the
whole set of possible string declarations?

$ cat long1.hs
{-# OPTIONS -cpp  #-}

s = "abc\
    \defg"

main = putStrLn s

$ ghc long1.hs

long1.hs:3:14:
    lexical error in string/character literal at character 'e'

$ cat long2.hs


s = "abc\
    \defg"

main = putStrLn s

$ ghc long2.hs
$ a.out
abcdefg
