Confusingly, you talk about comments above, but the real issue is that
your makepp apparently gives the ' special meaning.  For once "info
make" and "man 1p make" on my system agree on the semantics of ': none
at all.  From the latter:

  Early proposals stated that an "unquoted" number sign  was  treated  as  the
  start of a comment. The make utility does not pay any attention to quotes. A
  number sign starts a comment regardless of its surroundings.

So can you quote chapter and verse to show that there is anything to
fix?
