According to the Jamroot file if i'm to exclude some libraries from building Boost I should use --without-<library> when invoking bjam. However it looks like I'm doing something wrong as it seems that the libraries I asked bjam to skip are being built. Below is what I understood I should use if I wanted to exclude the Boost.Thread library:

smclemo@edin-angus /usr/src/boost_1_39_0

$ bjam link=static toolset=bfin target-os=elf --without-thread threading=single runtime-link=static stage

And below is a snippet from my build output indicating that we've attempted to build Boost.Thread:

...failed bfin.compile.c++ bin.v2\libs\thread\build\bfin-8.0.7.1\release\link-static\runtime-link-static\target-os-elf\threading-multi\win32\thread.doj...

bfin.compile.c++ bin.v2\libs\thread\build\bfin-8.0.7.1\release\link-static\runtime-link-static\target-os-elf\threading-multi\win32\exceptions.doj

".\boost/config/requires_threads.hpp", line 94: cc0035:  catastrophic error:

     ^

1 catastrophic error detected in the compilation of "libs\thread\src\win32\exceptions.cpp".

Compilation terminated.

cc3089: fatal error: Compilation failed

I'm guessing that I'm not using the correct switch, perhaps --without-Thread or --without-threads or something else is correct?
