Comment:

 If you use `-XCPP` then you are responsible for ensuring that the output
 of the C preprocessor is a valid Haskell program. Line continuations (`\`
 at the end of a line) are handled by the C preprocessor (so that you can
 define multi-line macros). See
 https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/options-
 phases.html#cpp-string-gaps.
