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
