v3 feedback and questions

[Martin von Loewis]

Being just an observer of the libstdc++ v3 development, I'll try to
answer your questions, anyway...

I don't think so. iostreams was always implemented on top of libio,
and this is the basis for meeting some compliance: cin/cout/cerr/clog
are required to be synchronized with the C files stdin/stdout/stderr.
In particular, this means that they need to share common buffering.

I'm not sure how this is supposed to work on a platform where we don't
implement the C library...

It has to stay in sync with libio, but that's it.

Sending it to the list has worked in the past, I believe. If the
traffic on the list increases, this might change.

There is always the risk that the code that was fine-tuned is thrown
out alltogether. If you accept that, I see no reason not to try to fix
it. My only contributions to libstdc++ where of that minor kind, and
they got all integrated.

Hope this helps,
Martin
