I got a bit confused with that.  How about this rewording?

  To help with the transition, Autoconf warns about makefiles that seem
  to use @code{datarootdir} without defining it.

(Or, if the heuristics aren't limited to makefiles, change "makefiles"
to "files" in the proposed rewording.)

These "# ..." lines aren't needed, surely.

Please reword to something like this:

  Usually one can easily change the makefile to accommodate both older
  and newer Autoconf releases:

As Stepan suggested, that last sentence is confusing.  I'd replace it
with something like "This is an exception to the usual rule that you
should not define a macro whose name begins with @code{AC_}."
