I recall that I did put PATH first originally, but it blew up because
I put /usr/xpg4/bin before /bin in my own PATH, and then the script
selected /usr/xpg4/bin/sh (an alias for ksh).  This blew up for users
that didn't have /usr/xpg4 installed on their box.  I then went to the
above solution.

However, the application I was using this for (gzip) was building
shell scripts for other users to run, where I wanted to prepend
"#!/bin/ksh".  This differs a bit from the curretly proposed
application, which is selecting the shell dynamically.  However, given
my experiences I'm still a bit leery of relying on the builder's PATH
except as a last resort.

Builders who really want to specify the shell can always set
CONFIG_SHELL; it overrides all that stuff.
