I think that by stealing CVS automake files you are putting

I'm afraid this bug is still here :( I've fixed it at least two
times but that was implicit in patches that aimed at replacing $ac_aux_dir
with $am_aux_dir defined below, and that were refused.
Because $ac_aux_dir is still used, it means the two first
setups ($ac_aux_dir/install-sh and $ac_aux_dir/install.sh) will
fail when $srcdir is absolute. See the explanation in the
comment below. IIRC, I believe Tom's plan is to drop the support for
intall.sh, and only use the missing setting.

This has never been used. Tom wants to expand paths at
make-time rather than configure-time so that a configured tree
can be moved around without reconfiguration (actually that still
can't work because $ac_aux_dir is expanded in other places too,
e.g. in ${am_missing_run}).
