I invoke ghc like this:


 {{{
 ghc --make -cpp -pgmLlhs2TeX -optL --pre -pgmPcpphs.compat -keep-tmp-files
 Functor.lhs
 }}}


 However, even with the -keep-tmp-files option enabled, ghc still does not
 keep the file it references in the error message below, which is annoying
 because it makes it less convenient to debug this error:


 {{{
 Chasing modules from: Functor.lhs
 Skipping  Category         ( ./Category.lhs, ./Category.o )
 Compiling Functor          ( Functor.lhs, Functor.o )

 /tmp/ghc16196.lpp:15:0: parse error (possibly incorrect indentation)
 }}}
