The find manual says it is "\!", not "-!".  The following corrects the
above and is slightly simpler:

find . -name "*.el" -a \! -name "*loaddefs.el" -a \! -name "ldefs-boot.el" | 
${ETAGS} -o $@ -

I think that inside a script quoting the ! is useless, as shell history
expansion is not enabled.  This would bring to this:

find . -name "*.el" -a ! -name "*loaddefs.el" -a ! -name "ldefs-boot.el" | 
${ETAGS} -o $@ -
