	* implement.h: Remove _pthread_find_entry() prototype.

	* private.c: Extend comments.
	Remove _pthread_find_entry() - no longer needed.

	* create.c (_pthread_start_call): Add call to TlsSetValue() to
	store the thread ID.

	* dll.c (PthreadsEntryPoint): Implement. This is called
	whenever a process loads the DLL. Used to initialise thread
	local storage.

	* implement.h: Add _pthread_threadID_TlsIndex.
	Add ()s around _PTHREAD_VALID expression.

	* misc.c (pthread_self): Re-implement using Win32 TLS to store
	the threads own ID.

+   We still need a means for pthread_self() to return its own thread
+   ID.
+
+   We use the Win32 Thread Local Storage mechanism. A single call to
+   TlsAlloc() will make available a single 32 bit location to every
+   thread in the process, including those created after the call is
+   made.
+
+   Provided we don't need to call pthread_self() after the Win32
+   thread has terminated we can use the DLL entry point routine to
+   initialise TLS for each thread. Or we can use pthread_once() in
+   pthread_create() to do it.
+
+   We can use either option. We'll use the DLL entry point routine.
