That works. :-)

Actually, there already is a qualifier which will select 
-fstack-protector, I had just forgotten about it:

  % gcc --help=common | grep stack
  -Wstack-protector           Warn when not issuing stack smashing 
protection
  -fdefer-pop                 Defer popping functions args from stack until
  -fomit-frame-pointer        When possible do not generate stack frames
  -fstack-check               Insert stack checking code into the program
  -fstack-limit               This switch lacks documentation
  -fstack-limit-register=<register> Trap if the stack goes past <register>
  -fstack-limit-symbol=<name> Trap if the stack goes past symbol <name>
  -fstack-protector           Use propolice as a stack protection method
  -fstack-protector-all       Use a stack protection method for every 
function

Cheers
