#11552: Warning from chrono that could helpfully be suppressed
------------------------------+-----------------------
 Reporter:  pbristow          |      Owner:  viboes
     Type:  Feature Requests  |     Status:  new
Milestone:  Boost 1.60.0      |  Component:  date_time
  Version:  Boost 1.59.0      |   Severity:  Cosmetic
 Keywords:  warning chrono    |
------------------------------+-----------------------
 Boost.Chrono is emitting warnings with GCC (5.1.0) that cannot be
 suppressed even using the following cxxflags in the user jamfile

       <toolset>gcc:<cxxflags>-Wno-deprecated-declarations
       <toolset>gcc:<cxxflags>-Wno-long-long
       <toolset>gcc:<cxxflags>-ftrack-macro-expansion=0 # Suppress note: in
 expansion of macro

 and they are repeated on every compilation which is quite annoying when
 reading the log file.

 For example:


 gcc.compile.c++ ..\..\..\bin.v2\libs\timer\build\gcc-mingw-5.1.0\debug
 \link-static\auto_timers_construction.o
 In file included from C:/Program Files/mingw-w64/x86_64-5.1.0-win32-seh-

                  from ..\..\../boost/cstdint.hpp:60,
                  from ..\..\../boost/ratio/config.hpp:13,

                  from ..\..\../boost/chrono/chrono.hpp:11,
                  from ..\..\../boost/timer/timer.hpp:14,
                  from
 ..\..\..\libs\timer\src\auto_timers_construction.cpp:23:
 ..\..\../boost/chrono/system_clocks.hpp:77:111: warning: use of C++11 long

  # define BOOST_SYSTEM_CLOCK_DURATION

 ..\..\../boost/chrono/system_clocks.hpp:77:90: note: in expansion of macro

 and more...

 It would be nice if the user would not see these (spurious?) warnings.
