This was a response to Andrey's question which was essentially about why we
need to do anything on the Boost level to "drop C++03 support" rather than
accomplishing the same thing organically by doing nothing and letting
libraries drop it one by one.
"Building Boost for C++11" is an action taken on the Boost level. It's not
doing nothing and letting libraries drop it one by one.
To preempt the follow-up question of why can't Log just alter its Jamfile to
build for C++11 by default - because all of its dependencies will then
refuse to install as it will attempt to build them for C++11, whereas
they'll attempt to build themselves for C++03.
