-/* 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.
-
-   1. 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 
-      24 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.
-
-   2. 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).
-   
-   3. 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.  */

-	// The picoChip instruction set has a divstep instruction which
-	// is used to perform one iteration of a binary division algorithm.
-	// The instruction allows 16-bit signed division to be implemented.
-	// It does not directly allow 16-bit unsigned division to be
-	// implemented. Thus, this function pulls out the common division
-	// iteration for 15-bits unsigned, and then special wrappers
-	// provide the logic to change this into a 16-bit signed or
-	// unsigned division, as appropriate. This allows the two
-	// versions of division to share a common implementation, reducing
-	// code size when the two are used together. It also reduces
-	// the maintenance overhead.
-
-	// Input:
-	//	r0 - dividend
-	//	r1 - divisor
-	// Output:
-	//	r0 - quotient
-	//	r1 - remainder
-	// R5 is unused
-	
-	// Check for special cases. The emphasis is on detecting these as
-	// quickly as possible, so that the main division can be started. If 
-	// the user requests division by one, division by self, and so on
-	// then they will just have to accept that this won't be particularly
-	// quick (relatively), whereas a real division (e.g., dividing a 
-	// large value by a small value) will run as fast as possible
-	// (i.e., special case detection should not slow down the common case)
-	//
-	// Special cases to consider:
-	//
-	//	Division by zero.
-	//	Division of zero.
-	//	Inputs are equal
-	//	Divisor is bigger than dividend
-	//	Division by power of two (can be shifted instead).
-	//	Division by 1 (special case of power of two division)
-	//
-	// Division/modulus by zero is undefined (ISO C:6.5.5), so
-	// don't bother handling this special case.
-	//
-	// The special cases of division by a power of 2 are ignored, since 
-	// they cause the general case to slow down. Omitting these
-	// special cases also reduces code size considerably.

-   by the task being deleted.  (This is a no-op on VxWorks 5, but
-   a major undertaking on AE.)
-
-   The task delete hook is only installed when at least one thread
-   has TLS data.  This is a necessary precaution, to allow this module
-   to be unloaded - a module with a hook can not be removed.
