I'm trying to build older versions of Emacs (e.g. 23.4) to test some
libraries against, but the build keeps failing at the makeinfo stage
(despite make's -k flag), apparently because of some texinfo error that
older versions didn't flag as such.
Is there a way to configure for a manual-less build without hacking the
Makefiles? The --without-makeinfo flag doesn't do what I thought.
