Subject: gnulib: revert copyright date changes in imported files
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1a024626f8e614a19d40894b27bd0b146a8d5f6b;p=thirdparty%2Fbinutils-gdb.git

gnulib: revert copyright date changes in imported files

Commit d01e823438 ("Update copyright dates to include 2025") changed the
dates in the gnulib imported source files, it probably shouldn't have.
Re-run update-gnulib.sh to restore those files.

gnulib/Makefile.in was also incorrectly modified, running the script
fixes that too.
