  17 dnl Substitutions aren't performed on the file in AC_SUBST_FILE,
  18 dnl so this is a cover macro to tuck the details away of how we cope.
  19 dnl We cope by having autoconf generate two files and then merge them into
  20 dnl one afterwards.  The two pieces of the common fragment are inserted into
  21 dnl the target's fragment at the appropriate points.
