The "online manuals" are a vital part of Emacs, so yes...

I agree with you. Perhaps the issue is the need to have _any_ version
of texinfo though.

The info files are already only deleted by `make maintainer-clean',
which "may require special tools to rebuild", so that's fine.
We don't check for autoconf etc either.

One problem I see is that the info files aren't in the CVS, so a fresh
checkout could fail to build. And also any update to the .texi files
will trigger a rebuild. So basically there are only problems with CVS
builds.

Perhaps a check early on in the Makefile will suffice, but it seems
a bit flaky?
