--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
altivec.h is clear:

/* If __APPLE_ALTIVEC__ is defined, the compiler supports 'vector',
   'pixel' and 'bool' as context-sensitive AltiVec keywords (in 
   non-AltiVec contexts, they revert to their original meanings,
   if any), so we do not need to define them as macros.  Also,
   avoid defining them as macros for C++ with strict ANSI, as
   this is not compatible.  */

#if !defined(__APPLE_ALTIVEC__) \
    && (!defined(__STRICT_ANSI__) || !defined(__cplusplus))
#define vector __vector
#define pixel __pixel
#define bool __bool
#endif

You can't use the non-standard 'vector' extension if you request strict c++11
mode.
