I ask again: would such patches be accepted? (Mike stated he would
remove stubs once GCC 4.1 is stable -- thanks -- so users wouldn't run
into problems often regardless.)

Ah yes, I see some that definitely apply to USE=vanilla builds. I'll see
if there's anything I can understand. :)

No, being able to use vanilla GCC as Gentoo's system compiler would be a
nice addition, and if it's agreed as a good idea I don't mind helping
out with getting it working, but I can live without it.

Being able to check software for unofficial compiler flags is for some
cases a must.

I repeat: two separate issues. They keep getting mixed up here.

The error is very clear:
 cc1: error: unrecognized command line option "-fno-stack-protector"

Maybe I have a little bit more confidence in people, sorry if that's
misplaced. :)
