+Update --version copyright message
+
+[ This is a backport of master commit dda7184. Output of
+contrib/gen-copyright-years.sh and dwz --version in this log message have been
+updated accordingly. ]
+
+In commit 9a663b4 "Update copyright" we've updated copyright in the sources,
+but not in the --version copyright message.
+
+Update the --version copyright message, using new script
+contrib/gen-copyright-years.sh that extracts the copyright years from the
+source files, and generates a file COPYRIGHT_YEARS containing define flags:
+...
+-DFSF_YEARS='"1992-2017"'
+-DRH_YEARS='"2001-2018"'
+-DSUSE_YEARS='"2019"'
+...
+resulting in:
+...
+$ dwz --version
+dwz version 0.13
+Copyright (C) 2001-2018 Red Hat, Inc.
+Copyright (C) 1992-2017 Free Software Foundation, Inc.
+Copyright (C) 2019 SUSE LLC.
+...
+
+2019-08-15  Tom de Vries  <tdevries@suse.de>
+
+	* contrib/copyright-lines.awk: New file.
+	* contrib/gen-copyright-years.sh: New file.
+	* COPYRIGHT_YEARS: Generate.
+	* Makefile (override CFLAGS +=, dwz-for-test): Add COPYRIGHT_YEARS
+	defines.
+	* dwz.c (version): Update copyright message using COPYRIGHT_YEARS
+	defines.
