patch 9.0.1971: macOS: FEAT_SOUND guard too restrictive Commit: https://github.com/vim/vim/commit/f59cbefd0aa1cda7d3fd5fbd02678e82ee155ad1 Author: Yee Cheng Chin <ychin.git@gmail.com> Date: Mon Oct 2 21:28:50 2023 +0200 patch 9.0.1971: macOS: FEAT_SOUND guard too restrictive Problem: macOS: FEAT_SOUND guard too restrictive Solution: check for older macOS support properly Fix macOS FEAT_SOUND guards to be less restrictive This allows +sound to work on older macOS platforms again. The +sound implementation uses APIs available in 10.6, but the code itself uses generics with type parameters which was only added in Xcode 7 / clang 7, which was released for macOS 10.11. This means as long as Vim is compiled under 10.11+, and using a deployment target >= 10.6, the feature will work. closes: #13251 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Yee Cheng Chin <ychin.git@gmail.com>
