+/* Cygwin versioning is relatively complicated because of its status
+   as a shared library.  Let's start with how versioning used to be done.
+
+   Historical versioning in Cygwin 16.0 to 19.5:
+
+   In the olden days of Cygwin, we had a dll major and minor version
+   and a registry version.  The major number started at 16 because the
+   "b15" GNU-Win32 release of the compiler tools was out when this
+   scheme was started.  We incremented the DLL name frequently (for
+   every official release) and towards the end of this period every
+   release used a different shared memory area to prevent DLLs from
+   interfering with each other (embedding a build timestamp into the
+   name of the shared memory area).  This turned out to be a Bad Idea
+   (tm) because people needed to mingle separate releases and have
+   them work together more than we thought they would.  This was
+   especially problematic when tty info needed to be retained when an
+   old Cygwin executable executed a newer one.
+
+   In the old scheme, we incremented the major number whenever a
+   change to the dll invalidated existing executables.  This can
+   happen for a number of reasons, including when functions are
+   removed from the export list of the dll.  The minor number was
+   incremented when a change was made that we wanted to record, but
+   that didn't invalidate existing executables.  Both numbers were
+   recorded in the executable and in the dll.
+
+   In October 1998 (starting with Cygwin 19.6), we started a new
+   means of Cygwin versioning: */
+
+      /* The DLL major and minor numbers correspond to the "version of

+
+/* Documentation on the innards of exception handling (i.e. from the
+   perspective of a compiler implementor) apparently doesn't exist.  Sigh.
+   However, the following came from Onno Hovers <onno@stack.urc.tue.nl>
+
+The first pointer to the chain of handlers is in the thread environment block
+at FS:[0].  This chain has the following format:
+
+typedef struct __EXCEPTION_FRAME
+{
+   struct __EXCEPTION_FRAME	*Prev;    /-* pointer to the previous frame *-/
+   PEXCEPTION_HANDLER		Handler; /-* handler function *-/
+}
+
+You register an exception handler in your compiler with this simple ASM
+sequence:
+   PUSH _MyExceptionHandler
+   PUSH FS:[0]
+   MOV  FS:[0],ESP
+An exception frame MUST be on the stack! The frame may have more fields and
+both Visual C++ and Borland C++ use more fields for themselves.
+
+When an exception occurs the system calls all handlers starting with the
+handler at FS:0, and then the previous etc. until one handler returns
+ExceptionContinueExecution, which is 0. If a handler does not want to handle
+the exception it should just return ExceptionContinueSearch, which is 1.
+
+The handler has the following parameters:
+ehandler (
+	   PEXCEPTION_RECORD erecord,
+	   PEXCEPTION_FRAME myframe,
+	   PCONTEXT context,		/-* context before and after *-/
+	   PVOID dispatch )		/-* something *-/
+
+When a handler wants to handle the exception, it has some alternatives:
+
+-one is to do do something about the exception condition, like emulating
+an invalid instruction, mapping memory where there was a page fault, etc.
+If the handler wants to have the context of the thread that causes the
+exception changed, it should make that change in the context passed to the
+handler.
+
+-the second alternative is to call all exception handlers again, indicating
+that you want them to clean up. This way all the __finally blocks get
+executed. After doing that you change the context passed to the handler so
+the code starts executing in the except block. For this purpose you could
+call RtlUnwind. This (undocumented) function calls all exception handlers
+up to but not including the exception frame passed to it. If NULL is passed
+as exception frame RtlUnwind calls all exception handlers and then exits the
+process. The parameters to RtlUnwind are:
+
+RtlUnwind (
+   PEXCEPTION_FRAME	endframe,
+   PVOID		unusedEip,
+   PEXCEPTION_RECORD	erecord,
+   DWORD		returnEax)
+
+You should set unusedEip to the address where RtlUnwind should return like
+this:
+	  PUSH 0
+	  PUSH OFFSET ReturnUnwind
+	  PUSH 0
+	  PUSH 0
+	  CALL RtlUnwind
+ReturnUnwind:
+	  .....
+
+If no EXCEPTION_RECORD is passed, RtlUnwind makes a default exception
+record. In any case, the ExceptionFlags part of this record has the
+EH_UNWINDING (=2),  flag set. (and EH_EXIT_UNWIND (=4), when NULL is passed as the end
+frame.).
+
+The handler for a exception as well as a for unwinds may be executed in the
+thread causing the exception, but may also be executed in another (special
+exception) thread. So it is not wise to make any assumptions about that!
+
+As an alternative you may consider the SetUnhandledExceptionFilter API
+to install your own exception filter. This one is documented.
+*/
+
+/* The January 1994 MSJ has an article entitled "Clearer, More Comprehensive
+   Error Processing with Win32 Structured Exception Handling".  It goes into
+   a teensy bit of detail of the innards of exception handling (i.e. what we
+   have to do).  */
