It conflicts with anything named as "vector" if you include AltiVec header file. It is especially a problem when using C++ vector type, that's why the keyword vector is not defined with C++: https://github.com/gcc-mirror/gcc/blob/master/gcc/config/rs6000/altivec.h#L45 The workaround is to #undef vector after including altivec.h, or directly in rte_altivec.h (with a compatibility breakage). In any case we should use only __vector keyword to allow such #undef.
