What exactly do you mean by C++03 is not supported ?

I mean that if testing of Boost is not supported for C++03, that effectively means that Boost does not support C++03.

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

...

In other words what do you think constitutes a C++03 library versus a C++11 library, such that a Boost C++03 library should not be supported ?

These things are obviously not necessarily mutually exclusive. A C++11 library is a lib that requires C++11 (be it libs a la std::array, or r-value references), a C++03-library is one that uses constructs not in the C++11 standard. Admittedly those constructs are only a handful. However, going forward, more and more constructs are being deprecated (and will subsequently be removed, cppreference.com tags quite some things deprecated). Then there are those libraries that don't support move semantics, while they could benefit from it.

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.
