The sentence I think is problematic is "This paragraph is transcribed below in honor of that request. Like the preamble it does not form part of the license." You can distribute Maxima under GPL + additional permissions, but then the above looks like a restriction to me ;). I.e. IMHO (And IANAL still applies) you cannot distribute code under the GPL and then on top claim "Well, if you live in such and such place you might need an export license". I have been looking at http://www.gnu.org/licenses/gpl-faq.html, but there are various questions and answers about "additional permissions" , but nothing in the direction of "additional restrictions" that seem to match. From an amateur standpoint this export restriction seems like an additional restriction that would make the code GPL incompatible. Maybe someone ought to contact FSF's licensing people?
