--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Guess we need something like:
-#elif defined(_ARCH_PWR8) && defined(__ALTIVEC__)
+#elif (GCC_VERSION >=3D 4005) && defined(_ARCH_PWR8) && defined(__ALTIVEC_=
_)
in libcpp/lex.c if clang doesn't support the altivec attribute and the
builtins.=
