Oh, I figured out that the warnings can be given in the project as off
and in the targets as on. This way the boost libraries are built with
warnings off and my libraries with warnings on.

project frame
     : requirements
        <warnings>off
     ;

lib hello_lib
     : source.cpp
     : <warnings>all
     ;	

However, there is still a problem with warnings in the boost include 
files. With MSVC they can be turned off by pragmas, in GCC not. However 
in GCC the boost files can be declared as system header files. I do it 
like:

project frame
     : requirements
        <warnings>off
            <toolset>gcc:<cxxflags>-Wno-system-headers
               <toolset>gcc:<cxxflags>"-isystem "$(BOOST_ROOT)
     ;

If there is a better way to achieve a clean compilation of own code with 
high warning level, please let me know.
