SysV make (was YAPQ (yet another prompt question))

Or better yet, rip the bogosity out of make in the first place.  It is
(somewhat) all right for make to use ${SHELL} as the shell to run
commands in the makefile, but it is then *not* all right for it to
arbitrarily import $SHELL from the environment.  J. Random User's login
shell has very little to do with the shell that should be used to run
make recipies.

If you are stuck with the SysV make and its bogus import (either because
you have no source code, or for some reason cannot modify it), you can
write your own `make' shell script that runs the real `make' but with
SHELL=/bin/sh:

	: import dependencies from .depend if appropriate
	: just like 4.3BSD-tahoe
	if [ -f .depend ]; then
		if [ -f makefile ]; then
			f="-f makefile -f .depend"
		else
			f="-f Makefile -f .depend"
		fi
		for i do
			case "$i" in -f*) f=;; esac
		done
	else
		f=
	fi

	SHELL=/bin/sh; export SHELL
	: ${MACHINE=`machine`}		# optional
	exec /bin/make $f ${1+"$@"}
