I did notice that a huge swathe of the cvs/* tags were identical to each
other, and the date embedded in the name sufficiently far from the
referenced commit to seem odd , tho I didn't know where the CVS repo
was, so I couldn't check whether they just mirrored the corresponding
CVS tags or not...

       update from main archive 961005

       Sun Oct  6 02:05:52 1996  Ulrich Drepper  <drepper@cygnus.com>

           * posix/getopt.c: Add casts to prevent warnings.
           * posix/regex.c: Likewise.


What makes them even more suspicious is that some similarly-named tags
with _earlier_ dates, refer to later commits... e.g.:

   (glibc) git describe cvs/libc-970604
   glibc-1.93-212-g779ae82

   (glibc) git show cvs/libc-970604 |head
   commit 779ae82ecdf88b7ed7c1f00d3ed3a639671c3c8d
   Author: Ulrich Drepper <drepper@redhat.com>
   Date:   Wed Apr 30 15:51:34 1997 +0000

       Update.

       1997-04-30 17:35  Ulrich Drepper  <drepper@cygnus.com>

           * math/libm-test.c: Implement test for exceptions.
           Partly due to Andreas Jaeger.
