That looks like it is a recommendation for Windows. Make is for Unix,
and environment variables are traditionally the way to configure things
on Unix.

Besides, CLASSPATH only needs to be set in this instance to configure
and build (and, even then, only if you are using something like jikes
that needs to know where the core classes are).

And remember that you can specifiy CLASSPATH on the command line of
configure, just like JAVAC etc.

I'm not sure what you mean, but `bootclasspath' is meaningless in
general. Other VMs don't support things like -Xbootclasspath.
