   Is this still needed after installing Ian's patch?

Yes, this is to work around the problem that runtest is invoked with
$0 set to simply "runtest" without including a patch.

Philippe De Muyter just posted a patch
(< 199710131730.TAA11370@mail.macqel.be >) which should fix that, but I
think his patch should be changed to search PATH rather than to rely
on the builtin ``type'' command.  There are examples of how to search
PATH in the top level configure script; here is one:

	  IFS="${IFS=	}"; save_ifs="$IFS"; IFS="${IFS}:"
	  for dir in $PATH; do
	    test -z "$dir" && dir=.
	    if test -f $dir/$prog; then
	      CONFIG_SHELL=$dir/$prog
	      export CONFIG_SHELL
	      break
	    fi
	  done
	  IFS="$save_ifs"
