building

[Peter T Greening]

/sigh... at least I know which direction to go now. Thank you very much for 
your time.  At this point I am hesident to try to RPM my way to a better gcc 
environment, and more inclined to chroot myself into a little hole and build 
my way out from source.  Of course this is alot of work, and I just want a 
gcc which doesnt generate errors such as "your gcc doesnt create 
executables".  Again /sigh, I have forgotten what I was trying to build in 
the first place that convinced me I needed to rebuild gcc.  Mabe I will rpm 
my way to happiness.. again, thanks for all your help.

laziness is the ultimate motivation of all good system administrators,
any time they can automate, out-source, or otherwise eliminate a task
from their regular routine, it allows them to be more lazy.  A truly 
lazy system admin would never have to do anything, because everything
would be either automated and done by the machine, or done by users.  
The education of users also fulfills this laziness goal, an educated
user will both be more productive, and require less of the admin.
