I am away from my home computer right now but I will push a local branch 
of Boost Build for clang under Windows/mingw when I get back ( another 
week ).

I am not a Boost Build expert so whatever little I have done is just a 
hack based on others.

I tried to get the Boost Build people interested in toolsets for clang 
on Windows in the past, but without success. Maybe you will be more 
successful. I wanted both a toolset for clang Windows/VC++ and clang 
Windows/mingw.

The basic hack of clang Windows/mingw is to take 'rule setup-threading' 
from gcc.jam, add it to clang-linux.jam, change 'case windows : option = 
-mthreads ;' to 'case windows : option = -pthread ;', and then change 
every invocation in clang=linux.jam of 'gcc.setup-threading' to just 
'setup=threading'.
