Yes, your suggested note would be helpful.

Older versions of Boost rarely work with newer versions of G++, especially in
C++11 mode, because noone tests Boost svn against GCC svn any more. Even if
the GCC 4.7 release notes had mentioned the change it wouldn't have made any
difference, I think Boost 1.47 had already been released when the change was
made and it would be too late to fix it.
Maybe we could add something to http://gcc.gnu.org/gcc-4.7/porting_to.html
about the change.
