I forgot that we can compile with pthreads on windows. At least the 
comments on the Jamfile says that.
"
# For the library variant that is not native on the build platform
# an additional tag is applied:
# boost_thread_pthread for the pthread variant on windows, and
# boost_thread_win32 for the win32 variant (likely when built on cygwin).
#
# To request the pthread variant on windows, from boost root you would
# say e.g:
# bjam msvc-8.0 --with-thread install threadapi=pthread

"

How have you built boost and how your user has build boost?
Which compile time flags are you using in your application and which is 
using your user?
Are you defining BOOST_THREAD_POSIX

You can start by following the  Windows specific bugs (or whatever bug 
as well) and pushing some PR for them. Once I have an idea of what kind 
of work you can do, I can request to give you the needed rights to 
commit your self any change and become a co-maintainer.
