//
// #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.
