Maybe something got misunderstood, then. My intention was to create a list of tasks that need to be done in order to reach the final goal of having TLS work. New binutils is one of those tasks. I also wanted to stress that each task needs an owner, otherwise it won't get done.

Is there any way for C_R to detect when it's in a position to blow up and/or give an intelligent message to the user? ScottReceived on Tue Mar 23 2004 - 22:26:56 UTC
