The number one issue has always been building the "new" build tools that
are required by new sources. In particular, this means:

	make
	gcc
	yacc
	lex
	config

There are probably others, but it's late, and I'm tired. Not all of them
change, release to release, but when they do, it's important to make sure
that you build with the new versions.
