From f283edc4827f6bfa82240e36433d7184ab106b0f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Andreas=20F=C3=A4rber?= Date: Sun, 27 May 2012 16:21:02 +0200 Subject: [PATCH] arch_init: Fix AltiVec build on Darwin/ppc MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Commit f29a56147b66845914d0a645bf9b4c5bb9a6af57 (implement -no-user-config command-line option (v3)) introduced uses of bool in arch_init.c. Shortly before that usage is support code for AltiVec (conditional to __ALTIVEC__). GCC's altivec.h may in a !__APPLE_ALTIVEC__ code path redefine bool, leading to type mismatches. altivec.h recommends to #undef for C++ compatibility, but doing so in C leads to bool remaining undefined. Fix by redefining bool to _Bool as mandated for stdbool.h by POSIX.
