Though the stack protector extensions (a.k.a ProPolice) are appeared upstream 
in GCC4, it was available for GCC 2.x and 3.x as a patch set, and some 
platforms (openbsd, maybe dragonfly?) are using it that way, so it could make 
sense.

BTW, is there a really working way to check if the used compiler is GCC4?
