I take it that this means that I have got clang compiler selected OK.

clang version 3.1 (tags/RELEASE_31/final 161181) (llvm/tags/RELEASE_31/final 161243)

but for a static build

I:\boost-trunk>b2 toolset=clang 
--build-dir=i:\boost-trunk variant=debug release
 link=static 
runtime-link=static
threading=multi 
--with-test  1>build_clang_static_libs_trunk_test_16-Nov-2012_1714.log 2>&1

produces (similar to a dynamic build)

C:/mingw32-dw2/include/c++/4.6.3  does contain cstddef

is starts saying // -*- C++ -*- forwarding header.

but 

    <cxxflags>-cxx-include-root="C:/mingw32-dw2/include/c++/4.6.3"

 doesn't seem to be in the search list above?  So I'm doing something wrong here.

Thanks
