mathicgb upload

[Doug Torrance]

Hi Anton!

I noticed that you set mathic to Done on the SoB page.  This was
actually a new request, but I'm wondering if it was even necessary.

A new RC bug [1] was filed against the version that you uploaded a
couple days ago.  I imagine they just grepped the exported symbols,
saw that they included symbols that cause problems like the one that
made mathicgb FTBFS, and filed the bug.

What they probably didn't realize was that we had already taken care
of it.  However, I had neglected to append "v5" to the library name,
so I pushed a new version to git with the requested change.

What do you think?  Should we upload the new version, or leave it as
it is in unstable and close the bug by hand?

Thanks!
Doug
