I think the right way is to require that all ports have a maintenance
person build the thing at least once a year for all supported platforms.

For such maintenance builds, I can trivially emit a list of hacks that
got triggered during the build.  Any hacks that don't show up in the
list for a couple of years get marked as "obsolete" and trigger a build
warning.  If nobody complains about the warning, then its gone.
Shouldn't take more than 3 or 4 years of disuse to get rid of the cruft. :)

How's that for an approach?
