//    #define switches
//      SIGSLOT_PURE_ISO      - Define this to force ISO C++ compliance. This also disables
//                      all of the thread safety support on platforms where it is
//                      available.
//
//      SIGSLOT_USE_POSIX_THREADS - Force use of Posix threads when using a C++ compiler other than
//                      gcc on a platform that supports Posix threads. (When using gcc,
//                      this is the default - use SIGSLOT_PURE_ISO to disable this if
//                      necessary)
//
//      SIGSLOT_DEFAULT_MT_POLICY - Where thread support is enabled, this defaults to multi_threaded_global.
//                      Otherwise, the default is single_threaded. #define this yourself to
//                      override the default. In pure ISO mode, anything other than
//                      single_threaded will cause a compiler error.
//
//    PLATFORM NOTES
//
//      Win32           - On Win32, the WIN32 symbol must be #defined. Most mainstream
//                      compilers do this by default, but you may need to define it
//                      yourself if your build environment is less standard. This causes
//                      the Win32 thread support to be compiled in and used automatically.
//
//      Unix/Linux/BSD, etc.    - If you're using gcc, it is assumed that you have Posix threads
//                      available, so they are used automatically. You can override this
//                      (as under Windows) with the SIGSLOT_PURE_ISO switch. If you're using
//                      something other than gcc but still want to use Posix threads, you
//                      need to #define SIGSLOT_USE_POSIX_THREADS.
//
//      ISO C++           - If none of the supported platforms are detected, or if
//                      SIGSLOT_PURE_ISO is defined, all multithreading support is turned off,
//                      along with any code that might cause a pure ISO C++ environment to
//                      complain. Before you ask, gcc -ansi -pedantic won't compile this
//                      library, but gcc -ansi is fine. Pedantic mode seems to throw a lot of
//                      errors that aren't really there. If you feel like investigating this,
//                      please contact the author.
//
//
//    THREADING MODES
//
//      single_threaded       - Your program is assumed to be single threaded from the point of view
//                      of signal/slot usage (i.e. all objects using signals and slots are
//                      created and destroyed from a single thread). Behaviour if objects are
//                      destroyed concurrently is undefined (i.e. you'll get the occasional
//                      segmentation fault/memory exception).
//
//      multi_threaded_global   - Your program is assumed to be multi threaded. Objects using signals and
//                      slots can be safely created and destroyed from any thread, even when
//                      connections exist. In multi_threaded_global mode, this is achieved by a
//                      single global mutex (actually a critical section on Windows because they
//                      are faster). This option uses less OS resources, but results in more
//                      opportunities for contention, possibly resulting in more context switches
//                      than are strictly necessary.
//
//      multi_threaded_local    - Behaviour in this mode is essentially the same as multi_threaded_global,
//                      except that each signal, and each object that inherits has_slots, all
//                      have their own mutex/critical section. In practice, this means that
//                      mutex collisions (and hence context switches) only happen if they are
//                      absolutely essential. However, on some platforms, creating a lot of
//                      mutexes can slow down the whole OS, so use this option with care.
//
//    USING THE LIBRARY
//
//      See the full documentation at http://sigslot.sourceforge.net/
//
//
// Libjingle specific:
// This file has been modified such that has_slots and signalx do not have to be
// using the same threading requirements. E.g. it is possible to connect a
// has_slots<single_threaded> and signal0<multi_threaded_local> or
// has_slots<multi_threaded_local> and signal0<single_threaded>.
// If has_slots is single threaded the user must ensure that it is not trying
// to connect or disconnect to signalx concurrently or data race may occur.
// If signalx is single threaded the user must ensure that disconnect, connect
// or signal is not happening concurrently or data race may occur.
