	When I do that I get:

	So I need to (re-?) install gcc-4.2.  How?

	Checking on what I've got (following your instructions) I
	found that I have version 2.5 of Xcode.

	That appears to be the latest version of Xcode that runs on
	Tiger.  The web page indicates that Xcode 2.5 dates from
	November 2007 which was about when I first installed Xcode.
	So re-installing Xcode 2.5 won't do any good.

	(On Friday I mistakenly tried installing Xcode 3.1.3 or something
	like that, but of course that won't/doesn't/didn't work on Tiger.)

	So how do I get gcc-4.2 for my OS? (Mac OS X 10.4.11).  Is this
	possible?
