+1.

As many others have said, Boost.Test is "special" in that the majority 
of Boost's tests depend on it.  Even breakages in develop are extremely 
painful in that they effectively halt progress for any Boost library 
which uses Test for testing.

As for testing in C++03 mode - that's easy, just use GCC's default 
compiler mode ;-)
