For PR automake/323:
* m4/depend.m4: Missing comma.
* tests/gcj4.test: New file.

Fix some bugs when using "$@" when there might be zero positional
arguments in cases where this matters.  Zsh doesn't support

* missing: Update from lib/missing.

No need for ${1+"$@"} workaround, as the command is never invoked with

Update from lib/missing.

No need for ${1+"$@"} workaround, as the command is never invoked with
zero arguments.  The workaround breaks with Zsh, so go back to "$@".
