From 0da546665075aefbb476e192ed64122d340164f4 Mon Sep 17 00:00:00 2001 From: Ned Deily Date: Mon, 18 May 2020 09:17:22 -0400 Subject: [PATCH] bpo-26317: Support OBJC and OBJCXX configure command line variables (GH-20176) Add support to the configure script for OBJC and OBJCXX command line options so that the macOS builds can use the clang compiler for the macOS-specific Objective C source files. This allows third-party compilers, like GNU gcc, to be used to build the rest of the project since some of the Objective C system header files are not compilable by GNU gcc.
