Re: AC_PROG_PERL (macro, docs, used in configure.in)

[Akim Demaille]

We face the same problem as with GNU M4:

Automake (which has too much hard coded knowledge on Autoconf) does
not dive into Autoconf's guts, and therefore does not know that
AC_PROG_PERL exists and AC_SUBST's PERL.  So it drops it.

Here is what autoscan looks like with the explicit AC_SUBST in
configure.ac:

~/src/ace % sed 1q autoscan                                       nostromo 9:41
