Hi Lynn,

the compiler options are set in tools/build/v2/tools/gcc.jam - but, I don't see -Wextra there. It appears that the thread library
adds it here:

        libs/thread/build/Jamfile.v2

if you remove the line that say:

        <toolset>gcc:<cxxflags>-Wextra

that option will not be passed to the compiler.

Note that I am not quite sure which Linux you have. If 3.2.2-5 refers to your kernel version, then it is of very little interest when 
building Boost.

HTH,
