How much does the MAU effect the performance of the above machines?
Is unix (as distributed) able to recognize the MAU when it is there
and take advantage of it? Do the C libraries (and other floating point
code) know when the MAU is there and are they able to take automatic
advantage of it or do you have to recompile everything? Are the unix
support programs (such as sum) able to automatically take advantage of
the MAU?

Bush is smart. First he's insured that he won't be assassinated by having
Quayle as his vice, Second he's managed to distract the american people
so he can dismantle the constitution and entrench his power.
