Hmmm - since C++ versions are backward compatible, almost any C++03
conforming program is also conforming to subsequent versions. The only
exceptions are a very few deprecations (like auto). This leads me to
not understand what it means to "drop C++03 support". If one want's to
compile all of boost with C++11, it should work - subject to the few
cases site above. I don't see any need for any action by anyone.

Has anyone tried to build all of boost with C++ set to version 11?

What are the results?

If I had nothing else to do, I could do it. But it's a moot question
for me in any case. Hmmm - then why am I replying here? I don't know.
