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>
