When bash interprets this code:

if [ ! -d $xtop/util -o ! -d $xtop/util/imake.includes ]; then
    echo "$progname"":  no X configuration files under $xtop"
    exit 1
fi

it says "[: too many arguments.", Bourne shell "[" works fine on the
same expression.

I think this is because the precedence of the ! operator is different
in bash than in sh.

Thanks.  Fixed.
