Recent versions of Autoconf generate "configure" scripts that do just
that, which is partly why I'm not so worried about the shell-function
issue even for Ultrix.  This also may help to explain why new
"configure" start up so slowly on older boxes -- you don't get this
functionality for free, unfortunately.

Do you recall whether /bin/sh5 was a standard part of Ultrix and was
installed on every Ultrix machine?  If /bin/sh5 was an option and
might not be installed, then there still might be an issue here.
