This isn't very convenient, because you can't run the 03 and 11 tests at the 
same time (and they go into the same directory).

What I use is this (in user-config.jam):

import feature ;
import toolset ;

using gcc ;

feature.subfeature toolset gcc : std : cxx0x cxx11 cxx1y cxx14 : optional 
composite propagated ;

feature.compose <toolset-gcc:std>cxx0x : <cxxflags>-std=c++0x ;
feature.compose <toolset-gcc:std>cxx11 : <cxxflags>-std=c++11 ;
feature.compose <toolset-gcc:std>cxx1y : <cxxflags>-std=c++1y ;
feature.compose <toolset-gcc:std>cxx14 : <cxxflags>-std=c++14 ;

using clang : : : <cxxflags>-Wno-variadic-macros 
<cxxflags>-Wno-c99-extensions ;

feature.subfeature toolset clang : std : cxx0x cxx11 cxx1y cxx14 : optional 
composite propagated ;

feature.compose <toolset-clang:std>cxx0x : <cxxflags>-std=c++0x ;
feature.compose <toolset-clang:std>cxx11 : <cxxflags>-std=c++11 ;
feature.compose <toolset-clang:std>cxx1y : <cxxflags>-std=c++1y ;
feature.compose <toolset-clang:std>cxx14 : <cxxflags>-std=c++14 ;

This allows me to run

    b2 toolset=gcc,gcc-cxx11,clang,clang-cxx11

for example.

-std=c++03 is, I believe, the default, but you can add it to the above if 
you like.
