-------------------------------+--------------------------------------------
 boost/concept_check.hpp contains two instances of assigning a variable to
 itself. In context, this is perfectly safe (since the code should never
 actually be executed), but it nonetheless triggers gcc's -Wself-assign,
 cluttering the build output for those who have that flag set, and breaking
 the build for those who also set -Werror. So far as I can tell, this code
 can be trivially rewritten to avoid the warning without any correctness or
 performance impact (see the attached patch).
