If you don't want complications, use the dll version of Boost.Threads
for Win32. You can use either the dynamically linked or statically
linked version on other platforms.
The reason I included a partially working (on Win32) version of a
statically linked Boost.Threads library is that some people *really*
want static linking; it's one of the most frequent Boost.Threads
requests. This version is for developers who:
a) Know that they don't really need tss cleanup, so they don't need to
call the cleanup functions (not recommended unless you're really sure
you know what you're doing);
b) Are statically linking Boost.Threads into their own dll, where they
can detect thread exit in their own dllmain function and can call the
appropriate cleanup functions;
c) Have other application-specific ways to detect thread exit (e.g.,
they create their own threads using a class other than boost::thread and
can call the appropriate cleanup functions when the thread function
d) Want to experiment with ways of adding full tss-cleanup support for a
future version of the statically linked Win32 Boost.Threads.
