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.
