Yup :)

Just as a brief heads-up (I meant to attach this to my previous mail).
Even after these two patches are applied, there is still one testsuite
failure with concept checks turned on (25_algorithms/unique/moveable.cc).

This failure is present because one of the testsuite structs
purposefully fails the concept checks (it only provides moveable copy
and assignmen, not true copy and assignment). I haven't decided the
neatest way of fixing this yet, but there is not "actual problem", just
a testsuite problem.
