+The AltiVec header typically defines the keywords "vector" and "bool" that
+can be used within vector code, however this is not really compatible with
+C++, so these tend to be undef'd in a C++ environment.
+
+This is what happens here, at least in our specific environment, so use the
+prefixed gcc/clang versions, which are available builtin, so the compilation
+does not fail.
