The clang toolset seems to be incomplete (or maybe just broken) as it does not 
honour the <ranlib> and <archiver> options used by gcc.jam to explicitly 
specify the tools. gcc.jam also has some  logic to query the full paths from 
gcc which clang(-linux).jam does not use either. Unfortunately, my Boost.Build 
knowledge ends here.
I was able to get things going by putting "C:/mingw32-dw2/bin/" into PATH and 
thus making

work. Not nice, especially if you want several toolsets, but the only solution 
for now, I fear.

I can use clang without the extra include flags. And <include> feature is 
broken, too.

For the record, the full invocation should be:

using clang : 3.1
            : e:/dev/apps/mingw32-dw2/bin/clang++
            : # options
                  <ranlib>e:/dev/apps/mingw32-dw2/bin/ranlib
                <archiver>e:/dev/apps/mingw32-dw2/bin/ar
            ;

as soon as <ranlib> and <archiver> work. But those should be autodetected as 
in gcc.jam

Yours,

Jürgen
