OK, I'm not a C++ guru an I assume I'm wrong. Btw, I don't really understand
what injection is, and I've been unable to see what's wrong regarding what I
read at the gcc-4.0/changes.html page. I can live with that, for sure, so don't
worry; for me, knowing the fact is that kind of declaration is no longer valid
is enough.

You say that -ffriend-injection won't solve this issue. The problem is that
this syntax was common use before and I have tons of software with those
"artifacts"... is there any "compatibility option" to handle them?

Thanks for your attention.
