Hi,
The current version of automake does not link/copy depcomp when invoked
with the --add-missing option even if it is required by the configure
script. The AM_DEPENDENCIES macro invokes depcomp, so I think it's
appropriate to copy the program whenever the macro is used as a part of
the configure script and not only when DEP_FILES is non-empty.
I was able to observe the problem when building libtool 1.4 after
regenerating files with current versions of autoconf and automake. As a
result, the shell complained of missing depcomp, even though `automake
--add-missing --copy' was invoked previously.
A patch follows. It was generated a few days ago but it applies to
automake 1.4g as of today cleanly.

* automake.in (seen_dependencies): New global.
(scan_one_autoconf_file): Set it when AM_DEPENDENCIES seen.
(handle_languages): Only check whether to include auto-dep code if
seen_dependencies set. Always require depcomp if the check is
enabled.
