  12 /* Cygwin versioning is relatively complicated because of its status
  13    as a shared library.  Let's start with how versioning used to be done.
  14
  15    Historical versioning in Cygwin 16.0 to 19.5:
  16
  17    In the olden days of Cygwin, we had a dll major and minor version
  18    and a registry version.  The major number started at 16 because the
  19    "b15" GNU-Win32 release of the compiler tools was out when this
  20    scheme was started.  We incremented the DLL name frequently (for
  21    every official release) and towards the end of this period every
  22    release used a different shared memory area to prevent DLLs from
  23    interfering with each other (embedding a build timestamp into the
  24    name of the shared memory area).  This turned out to be a Bad Idea
  25    (tm) because people needed to mingle separate releases and have
  26    them work together more than we thought they would.  This was
  27    especially problematic when tty info needed to be retained when an
  28    old Cygwin executable executed a newer one.
  29
  30    In the old scheme, we incremented the major number whenever a
  31    change to the dll invalidated existing executables.  This can
  32    happen for a number of reasons, including when functions are
  33    removed from the export list of the dll.  The minor number was
  34    incremented when a change was made that we wanted to record, but
  35    that didn't invalidate existing executables.  Both numbers were
  36    recorded in the executable and in the dll.
  37
  38    In October 1998 (starting with Cygwin 19.6), we started a new method
  39    of Cygwin versioning: */
  40
  41       /* The DLL major and minor numbers correspond to the "version of
  42          the Cygwin shared library".  This version is used to track important
  43          changes to the DLL and is mainly informative in nature. */
