Comment(by jeremyhu@…):

 Either -faltivec or #include <altivec.h> needs to be used.

 So the check for __VEC__ is ok so long as <altivec.h> is included (but
 it's not).

 The issue is still in the header file, and the 10.4u SDK shipped with
 newer versions of XCode (I checked 3.1.4) have that changed, but that
 doesn't do us much good.
