I think it may be a simple legal requirement that a statement of the
form "this exception E to some requirement R does not imply that other
reasons that R may hold are void" accompanies E not R.  IANAL though,
this is pure speculation on my part.

I'd say "have a lawyer do it for you" is a good guidebook.
Really, I don't think anyone can seriously recommend otherwise.

Well, it would not be good if the license would need to be changed for,
say, every other Autoconf version, due to some technical details that
changed.

I guess you're saying here that the definition is not strict enough to
prevent abuses, right?
