[Maxima] gamma function test suite failures

Yes, $numer is set to T within the function closeto in the file rtest14.mac.

Thank you very much for the value. I adjust the expected precision to 3.0e-15.

At the moment I am searching for a bug in bffac or $bern (full precision after
second call to bffac). See also the last bug report.

Until now I have no idea, what could be the reason for this bug.

(%i2) gamma(1/3)- 2.678938534707748;

(%o2) gamma(1/3)-2.678938534707748
(%i3) gamma(1/3)- 2.678938534707748, numer;

(%o3) 2.220446049250313e-15

Does closeto locally set numer to true?
