+/* Windows32 threads specific definitions. The windows32 threading model
+   does not map well into pthread-inspired gcc's threading model, and so
+   there are caveats one needs to be aware of.
+. The destructor supplied to __gthread_key_create is ignored for
+      generic x86-win32 ports. This will certainly cause memory leaks
+      due to unreclaimed eh contexts (sizeof (eh_context) is at least
+bytes for x86 currently).
+      This memory leak may be significant for long-running applications
+      that make heavy use of C++ EH.
+      However, Mingw runtime (version 0.3 or newer) provides a mechanism
+      to emulate pthreads key dtors; the runtime provides a special DLL,
+      linked in if -mthreads option is specified, that runs the dtors in
+      the reverse order of registration when each thread exits. If
+      -mthreads option is not given, a stub is linked in instead of the
+      DLL, which results in memory leak. Other x86-win32 ports can use
+      the same technique of course to avoid the leak.
+. The error codes returned are non-POSIX like, and cast into ints.
+      This may cause incorrect error return due to truncation values on
+      hw where sizeof (DWORD) > sizeof (int).
+. We are currently using a special mutex instead of the Critical
+      Sections, since Win9x does not support TryEnterCriticalSection
+      (while NT does).
+   The basic framework should work well enough. In the long term, GCC
+   needs to use Structured Exception Handling on Windows32.  */

+// Here are C++ run-time routines for guarded initialization of static
+// variables. There are 4 scenarios under which these routines are called:
+//
+//   1. Threads not supported (__GTHREADS not defined)
+//   2. Threads are supported but not enabled at run-time.
+//   3. Threads enabled at run-time but __gthreads_* are not fully POSIX.
+//   4. Threads enabled at run-time and __gthreads_* support all POSIX threads
+//      primitives we need here.
+//
+// The old code supported scenarios 1-3 but was broken since it used a global
+// mutex for all threads and had the mutex locked during the whole duration of
+// initialization of a guarded static variable. The following created a
+// dead-lock with the old code.
+//
+//      Thread 1 acquires the global mutex.
+//      Thread 1 starts initializing static variable.
+//      Thread 1 creates thread 2 during initialization.
+//      Thread 2 attempts to acquire mutex to initialize another variable.
+//      Thread 2 blocks since thread 1 is locking the mutex.
+//      Thread 1 waits for result from thread 2 and also blocks. A deadlock.
+//
+// The new code here can handle this situation and thus is more robust. However,
+// we need to use the POSIX thread condition variable, which is not supported
+// in all platforms, notably older versions of Microsoft Windows. The gthr*.h
+// headers define a symbol __GTHREAD_HAS_COND for platforms that support POSIX
+// like condition variables. For platforms that do not support condition
+// variables, we need to fall back to the old code.
+// If _GLIBCXX_USE_FUTEX, no global mutex or condition variable is used,
+// only atomic operations are used together with futex syscall.
+// Valid values of the first integer in guard are:
+// 0                              No thread encountered the guarded init
+//                                yet or it has been aborted.
+// _GLIBCXX_GUARD_BIT             The guarded static var has been successfully
+//                                initialized.
+// _GLIBCXX_GUARD_PENDING_BIT     The guarded static var is being initialized
+//                                and no other thread is waiting for its
+//                                initialization.
+// (_GLIBCXX_GUARD_PENDING_BIT    The guarded static var is being initialized
+//  | _GLIBCXX_GUARD_WAITING_BIT) and some other threads are waiting until
