GiNaC 0.6.4 is on the wire.

[Richard B. Kreckel]

Hello, folx!

I justed tagged GiNaC 0.6.4 and uploaded it to the usual places.  No new
functionality was introduced.  During the last weeks we ran the complete
check-suite thousands of times and were somewhat surprised to find a  
couple of nasty bugs.  Those have been killed and now the check-suite
doesn't seem to find any more.  Until somebody decides to re-introduce
them...

Here is the entry from the NEWS file:

* Complete revamp of methods in class matrix.  Some redundant (and poor)
  implementations of elimination schemes were thrown out.  The code is now
  highly orthogonal, more flexible and much more efficient. 
* Some long standing and quite nasty bugs were discovered and fixed in
  the following functions:  add::normal(), heur_gcd(), sr_gcd() and
  Order_eval() (thanks to Bernard Parisse).

Enjoy
   -richy.
