 Current clang issues warning in floating_point_comparison.hpp:

 {{{
 warning: unused variable 'check_is_close
 warning: unused variable 'check_is_small
 }}}

 There seems to be similar report for GCC in #2390


 The only way to deal with it in clang is to wrap the Boost.Test headers
 with

 {{{
 #ifdef __clang__
 #pragma clang diagnostic push
 #pragma clang diagnostic ignored "-Wunused-variable"
 #endif

 #include <boost/test/...>

 #ifdef __clang__
 #pragma clang diagnostic pop
 #endif
 }}}

 Perhaps it is possible to solve it in the library, so users don't have to
 deal with it.
