I propose the following:
1. Leave Configure as it is, this also to simplify integration
to older versions, as Configure is still shared amongst all
2. Make hints/machten.sh exit with a warning for any perl
higher than 5.8.x. This exit will have the same effect as
you intended with the change to Configure: it won't build
3. Add a note to README.machten that 5.8.x is the last perl
to support machten and only apply that to 5.8.x and below
4. Replace the content of README.machten with the patch you
supplied for blead and up
