//
// #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.
