I don't understand what the last sentence refers to.  


I don't really understand why you reversed these options.  The order
was on purpose, e.g.:

    --output | -o )
       test $# = 1 && eval "$exit_missing_arg"
       shift
       outfile=$1
       shift ;;
    --output=* | -o* )
       outfile=$optarg
       shift ;;

and your patch makes this the converse:

    --output=* | -o* )
       outfile=$optarg
       shift ;;
    --output | -o )
       test $# = 1 && eval "$exit_missing_arg"
       shift
       outfile=$1
       shift ;;

but then you broke `autoconf -o foo.out' while still support `autoconf
-ofoo.out'.  Sure, you win the possibility of having abbreviation of
long options, but it is on purpose that I dropped this.  The
equivalence of `-ofoo' and `-o foo' is more important.  And if we want
both we need three cases.  That's too much to pay (maintenance etc.).

So unless I misunderstood something, this patch breaks something I
meant :(
