Use $(), not ${}, for Make variables.

of egrep and fgrep.  Omit unnecessary -E and -F.
Fix quoting typo -- "fgrep '\$${'" should have been "fgrep '$${'".

For PR automake/323:
* m4/depend.m4: Missing comma.
* tests/gcj4.test: New file.
* tests/Makefile.am (TESTS): Add gcj4.test.
Reported by David Pashley.

* tests/defs (confiugre.in): Don't double-quote $me.

`am__sinclude' instead of `sinclude' as package name.

Fix some bugs when using "$@" when there might be zero positional
arguments in cases where this matters.  Zsh doesn't support
the workaround ${1+"$@"} that has been used by Automake since

invoked with zero arguments.

* missing: Update from lib/missing.

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