Case of "Language" pragma - bug?

I'm using GHC 6.6.1. The manual says: "Pragmas all take the form {-# word ... #-} where word indicates the type of pragma, and is followed optionally by information specific to that type of pragma. Case is ignored in word." However, when I use "Language CPP" instead of "LANGUAGE CPP" in the pragma, the pragma is ignored. Is this a documentation bug? To test the problem, one can use "ghc --make testpragma1.hs" and "ghc --make testpragma2.hs" on the following: -- Robin Bate Boerop
