+/* 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 method
+   of Cygwin versioning: */
+
