Ping !

I need to use target alternatives with multiple compilers so I write, as 
part of my jamfile:

test-suite somelib
    :
         [ compile some_source.cpp ]
    ;

test-suite somelib_gcc
    :
         [ compile some_source.cpp
           : <cxxflags>-std=c++0x
           : some_source_gcc
         ]
    :
    <toolset>gcc-4.3.0
    <toolset>gcc-4.4.0
    <toolset>gcc-4.5.0
    <toolset>gcc-4.5.2
    <toolset>gcc-4.6.0
    ;

test-suite somelib_gcc ;

But some_source never gets compiled again with the -std=c++0x option for 
the gcc compilers mentioned. Can not target alternatives be used with 
multiple compilers ?
