[Maxima] Maxima 5.16.3 release

[Robert Dodier]

Hello,

I have tagged Maxima 5.16.3 in cvs as version-5_16_3 and generated
tar.gz, src.rpm, and rpms and posted them to the SF file manager.
http://sourceforge.net/project/showfiles.php?group_id=4933

This release should fix some minor issues.
(1) fix bug in is_isomorphic in graphs package
(2) fix share test suite error caused by missing rtest_interpol
(3) some other minor bug fixes

If there aren't too many complaints about this version,
it will become the first advertised 5.16 release.

HTH

Robert Dodier
