What is `aclocal' trying to tell me? ``error: m4_defn: undefined macro: _m4_divert_diversion''

[Thomas Schwinge]

Hello!

I used to use this successfully with GNU Automake 1.10, but now I'm on a
system where only 1.9 is available, which i supossed to work and be
supported as well.

But now, what is `aclocal' trying to tell me?

#v+
$ AUTOMAKE=automake-1.9 ACLOCAL=aclocal-1.9 autoreconf -vfi
