You are saying then that what you mean by "C++03 is not supported" is
compiling in C++03 mode.

I also think that Boost libraries should successfully compile in at
least C++11 mode. But I hope you realize that is different from saying
that C++03 libraries, meaning libraries not using C++11or above
constructs or libraries, should not be part of Boost.
