patch 9.0.1685: silence Python 3.11 depreciations for gcc Commit: https://github.com/vim/vim/commit/422b9dcbfadcd5c1dfad982f9782563915398430 Author: Philip H <47042125+pheiduck@users.noreply.github.com> Date: Fri Aug 11 22:38:48 2023 +0200 patch 9.0.1685: silence Python 3.11 depreciations for gcc Problem: Python 3.11 interface throws deprecation warnings Solution: ignore those warnings for gcc and clang Python 3.11 deprecation warnings are already silenced for clang using the pragma ``` # pragma clang diagnostic ignored "-Wdeprecated-declarations" ``` However those warnings are also emitted when using gcc. To avoid them for both compilers, change use the __GNUC__ ifdef, which is defined for gcc as well as clang. Additionally, instead of using the "clang diagnostic ignored" pragma, let's make use of 'GCC diagnostic ignored' which is again supported by clang and GCC closes: #12610 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Philip H <47042125+pheiduck@users.noreply.github.com>

The files in this directory come from the xdiff implementation in git.
You can find it here: https://github.com/git/git/tree/master/xdiff
The files were last updated March 17, 2023 from git release v.2.40.0

This is originally based on libxdiff, which can be found here:
http://www.xmailserver.org/xdiff-lib.html

The git version was used because it has been maintained and improved.
And since it's part of git it is expected to be reliable.

The code is distributed under the GNU LGPL license.  It is included in the
COPYING file.

Changes in these files were made to avoid compiler warnings.

The /* */ comments are kept to make syncing to a newer version easier, do not
change them to // comments!

The first work for including xdiff in Vim was done by Christian Brabandt.
