[Ecls-list] Latest changes

[Juan Jose Garcia Ripoll]

* Fixed configure.in: --with-system-* did not always set the right flags.

* Implemented slot-definition objects. This is an important part of the 
MOP which allows one to query the slots of a class and alter their order 
in an structured way.

Hmm... Funny how a horrible change with lots of bootstrap problems ends 
up described in such a small paragraph :-)

P.S.: I will be away in the following two weeks, with maybe ocasional 
access to the internet.
