That sounds to me like you want the GCC team to keep their bugs forever when 
those bugs mask bugs in your code, so that you won't have to fix your bugs. 
Hopefully you didn't mean something quite so insane.

And what happens the day you need to compile that code with another compiler? 
Do you consider vendor lock-in through embrace-and-extend tactics to be a good 
thing when a free software project does it?
