I built Maxima using signbfloat : false. The test suite reports two problems

in rtest16; here is one problem testsuite problem (the other is similar):

OK with signbfloat : true:

(%i1) limit((%pi*4^N*N!^2)/(2*2^(2*N)*gamma(N+1/2)*gamma(N+3/2)), N, inf);

(%o1) 0

Not OK:

(%i2) signbfloat : false$

(%i3) limit((%pi*4^N*N!^2)/(2*2^(2*N)*gamma(N+1/2)*gamma(N+3/2)), N, inf);

Is log(4) - 2 * log(2) positive, negative, or zero? zero;

Is 2 * log(2) - log(4) positive, negative, or zero? zero;

(%o3) 0
