Thanks Paul for your tutorial, however I believe that if someone puts -Ogv in
the link phase it ought to be recognized as -nc.  It is certainly less 
cumbersome for a user to carry around 1 set of options than 2, and it is
more intuitive.  Getting it wrong can also make your machine perform and look 
VERY bad.  I also don't expect a general user to understand everything that
is happening at this level to know to use 2 different sets of options.   
Additionally, the fact that the linker doesn't complain about -Ogv gives a 
false sense of security.
