Bad error message for FFI declaration with no -fffi flag
If I compile:
module Ccall where
import Foreign.C.Types
foreign import ccall "stdio.h putchar"
putchar :: CInt -> IO CInt
I get:
$ ghc-6.8.1 -c -fext-core Ccall.hs -no-recomp
Ccall.hs:5:8: parse error on input `import'
A better error message would be to suggest passing the -fffi flag.
