  * Make everything build with ghc-6.6 and 6.4
  No code changes, just cpp for new LANGUAGE pragmas
  and not using a RULE with a funky LHS for ghc-6.4 which didn't allow it.

    M ./Data/ByteString.hs -1 +11
    M ./Data/ByteString/Char8.hs -1 +8
    M ./Data/ByteString/Internal.hs -1 +5
    M ./Data/ByteString/Lazy/Internal.hs -1 +5
    M ./Data/ByteString/Unsafe.hs +4
    M ./bytestring.cabal -1 +2
