Comment (by ballapete):

 `libtool @2.4.7_0` still has problems:

 {{{

 }}}

 The bug is in `libtool-2.4.7/build-aux/git-version-gen`:

 {{{
    74   me=$0
    75
    76   year=`expr "$scriptversion" : '\([^-]*\)'`
    77   version="git-version-gen $scriptversion
 }}}

 as this output shows:

 {{{
 ++ /bin/sh -x build-aux/git-version-gen .tarball-version
 + scriptversion=2022-01-27.18
 + me=build-aux/git-version-gen
 ++ expr 2022-01-27.18 : '\([^-]*\)'
 expr: brackets ([ ]) not balanced
 + year=
 + version=git-version-gen 2022-01-27.18
 }}}

 This expression works for me in old bashes, version 3.x, and returns the
 value of year, i.e. 2022. The variable is exactly once used here:
 `Copyright (C) ${year} Free Software Foundation, Inc.`. Version of
 `/bin/sh` is:

 {{{
 GNU bash, version 2.05b.0(1)-release (powerpc-apple-darwin8.0)
 }}}

 `echo $scriptversion | cut -d - -f 1` can deliver the searched for value.
