patch 9.1.0842: not checking for the sync() systemcall Commit: https://github.com/vim/vim/commit/8bb5eaf019bc46e3b20e1509d88c07655f1632cd Author: Jonas Sortie Termansen <sortie@maxsi.org> Date: Mon Nov 4 20:32:27 2024 +0100 patch 9.1.0842: not checking for the sync() systemcall Problem: not checking for the sync() systemcall Solution: check for sync in configure script, fix related #ifdefs (Jonas Termansen) It's better to check for features directly rather than maintaining a denylist of operating systems without them. closes: #15985 Signed-off-by: Jonas 'Sortie' Termansen <sortie@maxsi.org> Signed-off-by: Christian Brabandt <cb@256bit.org>
