Short story:
To make delta debugging more useful, gcc's
STL system headers should all compile without
warnings at the highest error checking level
without the use of hardcoded warning suppressions in the compiler
based on whether the code is in a system header or not

This question should have been sent to gcc-help, not here.
But as long as I'm answering:
It's std::cout now, according to the C++ standard.
If you want to compile old code that wasn't aware of std

Hmm. For some reason that reminds me of the 'final'

Just curious -- how did you build your cross-compiler?
Do toolchains built by crosstool have this problem?

Dunno who else is doing it, but I'm trying to do a realtime diary of
the gcc summit for the benefit of those who couldn't come. It's

I don't promise that it's legible or useful, but it might give some
of the flavor, at least.
