I had again a look at the problem. I have solved the problem in
SIMPTIMES. Maxima no longer has a problem with unsimplified 0^a
expressions and I get no problems with the testsuite and
share_testsuite.
But there is a next problem. Maxima will handle 0^a like any other
symbolic expression. Therefore, we get e. g. 0^a-0^a --> 0. We get some
more correct results, but we get wrong results too.
Furthermore, the initial problem of sum(0^i, i, 0, n) -> 0 is not
solved. We will get again 0. I have to look for the reason.
So more work is needed.
