In this case, if Zack now determines that irix5 hasn't worked since
before 2.95, I think 3 and 4 would be satisfied.  Perhaps #4 should
read "noticed" instead of "notices" ;-)

#3 is void if, say, it worked as recently as two releases ago.
#4 is void if, say, people have complained about it not working.

Again, I like the idea of adding a syntaxically erroneous comment to
such files.  It keeps the history, encourages volunteerism, sets
proper expectations, yet prevents the platform from being used while
it is in a known unusable state.
