+
+   WINDOWS CE: There is a collection of Windows CE functions to simulate
+   semaphores using only a mutex and an event. As Windows CE events cannot
+   be named, these simulated semaphores cannot be named either.
+
+   Implementation notes:
+   1. All required internal data structures are allocated on the process's heap.
+   2. Where appropriate, a new error code is returned (see the header
+      file), or, if the error is a Win32 error, that code is unchanged.
+   3. Notice the new handle type "SYNCHHANDLE" that has handles, counters,
+      and other information. This structure will grow as new objects are added
+      to this set; some members are specific to only one or two of the objects.
+   4. Mutexes are used for critical sections. These could be replaced with
+      CRITICAL_SECTION objects but then this would give up the time out
+      capability.
+   5. The implementation shows several interesting aspects of synchronization, some
+      of which are specific to Win32 and some of which are general. These are pointed
+      out in the comments as appropriate.
+   6. The wait function emulates WaitForSingleObject only. An emulation of
+      WaitForMultipleObjects is much harder to implement outside the kernel,
+      and it is not clear how to handle a mixture of WCE semaphores and normal
+      events and mutexes. */
