Boosters,

    In boost/thread/src/pthread/thread.cpp we see extern "C" {}
around code such as tls_destructor.  Is this needed so it
interfaces w/ native pthread local storage?
     When a vendor program is built against a specific version
of boost it usually becomes necessary to isolate other users
via a namespace.  However, anything with extern "C"
style defeats this.  Aside from explicit linking to native c
api's are there reasons for this; also what's considered the best
style to isolate different versions -- currently we modify every header
with a version-ed namespace wrapper.

thanks!
