[GiNaC-list] Release 1.6.2

Hi everybody, GiNaC 1.6.6 is out and available. The changes are the following: * Fixed the parser to read GiNaC::lst again. * Fixed a compile warning (relevant to openSUSE build). * Fixed a bug concerning the subsitutions in indexed expressions (subs_options::no_index_renaming was ignored). As always, this release can be downloaded from http://www.ginac.de/Download.html Regards, Jens
