[Boost-build] disabling warnings in boost headers

Hi,

I have a high warning level in my project. It leads to lots of warnings 
in stl and boost includes. How do I filter warnings in the system 
include files and in boost?

On MSVC I can suppress them by pragmas. However there is no such pragmas 
in GCC. I tried to use -Wno-system-headers and -isystem to give the root 
boost directory as the system include directory. However, I still get a 
lot of boost warnings. It seems that -isystem only disables warnings in 
the BOOST root include directory.  Not in the subdirectories. Adding the 
subdirectories does not help.

My Jamfile has the following:
