Yes, currently, it excludes -framework, and I thought I had made it only 
error on -l, but I must have lost that change along the way.

I think I am just tired of this one, sorry. :) If you can convince Brad 
or Ken to make the change that would be fine with me.  Basically, I/we 
want people to set CMP0003 to NEW or set the minimum required cmake to 
2.6, and if it links for them they are done.   I am more concerned with 
users than developers. If a user builds some existing package with CMake 
that was released prior to CMP0003, I don't want them to get blasted 
with warnings, and I want it to just work.  That is what we have now.
