Remaining host configuration fragments

Yes.

In contrast with some other folks, I would even be willing to say
something like this: "Even though we know there are people out there
who still use Irix 5, we are dropping support for it in GCC 3.1.
You can still use GCC 3.0 (or earlier) there, of course."

In some cases, we are still trying to support systems with GCC that
the operating system vendors stopped supporting years ago.  To me,
this is not an optimal use of scarce resources.

I don't have any good bright-line criteria for making that decision,
though.
