I've updated my not yet approved package of mathomatic to the latest upstream version.
http://xarch.tu-graz.ac.at/publ/cygwin/release/mathomatic/ (also via setup at http://xarch.tu-graz.ac.at/publ/cygwin/)
It has the wanted changes from Volker, for which it got a GTG, and it has 2 votes.
http://rpmseek.com/rpm-pl/mathomatic.html?&cs=mathomatic:PN:0:0:0:0 finds only a PLD Linux distro, so it needs 3 more votes.
+1. This looks very useful.
