Re: wxmaxima not functional, needs upgrade

Hi,

To add to the above, with parallel/openmp installed, latest wxmaxima
builds right away; for whatever reasons, while it finds the include
files and compiles them OK, the lengthy link command does not include
'-lomp' . After I added it, the build was OK and the resulting
executable fully functional, to the best of my initial tests of
course.
