Subject: le Makefile peut être utilisé sur Solaris, OSX et Linux. Par dégaut,
 c'est pour linux.

ivy.c corrige un unbindmsg

ivyprobe: -n pour le nom de l'agent, -v pour la version de la lib

ivytcl: plein de problèmes réglés, d'autres introduits, notamment pour la
gestion de la boucle d'évéenents sous windows ...

Test.tcl déplacé dans les exemples
