Ahhhh.  So it just links the gcc command to whatever version of gcc is 
active.  Kewl !!  That makes sense.

I learned something today.  Given my age, I may forget it tomorrow but 
at least I know it today.  lol

I do wish there was some way to find files that are not needed or used 
tho.  I would still go through the files and delete them manually but it 
would be nice, especially on my old rig which has a pretty old install.  
I bet /etc would have quite a few of them.

Thanks to you and Neil too.
