} Indeed, and I believe that I've had tests misleadingly fail through
} running `make test' before `make install' as a result of that.

You shouldn't have.  `make test' explicitly calls zsh by full path and
passes it ztst.zsh by name.

You might have had failures trying to run tests by hand with
	./ztst.zsh B01cd.ztst
or some such, but the "right" way to do that is
	make test TESTNUM=B01

} Shall I change it then?

I'm not sure it'll help, as many OSs won't accept more than one argument
after the command path when interpreting a #! line.  (That's likely why
you are having trouble with `env perl -w'.)

} We can persuade emacs to use the right mode using the other method:
} 
}   # Local Variables:
}   # mode:cperl
}   # End:
} 
} should do it.

Please don't.  I find it aesthetically displeasing to have that cruft
at the end of every file, and I hate having emacs stop during file load
to ask whether it should pay attention to it, and it's not secure to
simply always accept it.  I'd rather just type M-x cperl-mode if emacs
has got it wrong.

} If we use configure, presumably that would mean having (say)
} Utils/helpfiles auto-generated from Utils/helpfiles.in?  My vote is
} for that option.

Yes, that would be it, but my vote is still to avoid mucking with this
in configure.  Maybe something like the following, run through the
just-compiled zsh?

--- 8< --- snip --- 8< ---
# Src/zsh -f path_to_this_file path_to_file_to_fix ${bindir}
setopt nobanghist
command=( $(sed -n -e '1s/^#!//p' $1) )
if [[ -n "$command" ]]; then
    if [[ ${command[1]:t} == zsh ]]; then
	command[1]=$2/zsh
    else
	command[1]=$(whence -p ${command[1]:t})
    fi
    if [[ -n "$command[1]" ]]; then
	echo "#!$command" > $1.fix &&
	sed -e 1d $1 >> $1.fix &&
	mv $1 $1.orig &&
	mv $1.fix $1
    fi
fi
