I don't think this last sentence is helpful.  gengtype doesn't operate
by combining two other languages to get a third; it just looks to see
what roots are used by each particular language.  List in $gtfiles the
actual files used by the language that have GTY markers, except for
backend files (they're supplied automatically).

Some code samples (and exact copies of error messages) would help
better explain any remaining problems you're seeing.
