From 113427ff8d5e05e685ddf60861e4c9cabbb8e2df Mon Sep 17 00:00:00 2001 From: Ronald Oussoren Date: Tue, 15 Nov 2022 12:07:29 +0100 Subject: [PATCH] GH-95283: Add note about compilers in Mac/README.txt The build machinery assumes that the compiler that's used to build on macOS includes an SDK that's at least as new as the OS version on the build machine.
