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
OK. Untouched.
Yes, but certainly do put some comments in the appropriate unit (OldConfig.U, I think, offhand.)
That's up to you.
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
Or maybe don't even bother, though certainly remove or reword Dominic's promise to help fix any problems!
After all, there's a difference between not supporting something and going out of our way to un-support it.
Done. See patch below for hints/machten.sh and README.machten. It applies against perl-current and 5.6.3. I have not checked any other distributions.

+MachTen is no longer supported by its developers, Tenon Intersystems.
+A UNIX environment hosted on Mac OS Classic, MachTen has been
+superseded by Mac OS X and by BSD and Linux implementations for Macintosh
+hardware.
+The final version of Power MachTen, 4.1.4, lacks many features found in
+modern implementations of UNIX, and has a number of bugs.
+These shortcomings prevent recent versions of Perl from being able to use
+extensions on MachTen, and cause numerous test suite failures in the
+perl core.
+
+In September 2003, a discussion on the MachTen mailing list determined
+that there was no interest in making a later version of Perl build
+successfully on MachTen.
+Consequently, support for building Perl under MachTen has been suppressed
+in Perl distributions published after February 2004.
+The hints file, F<hints/machten.sh>, remains a part of the
+distributions for reference purposes.
