+Add new method to judge whether <altivec.h> is needed
+
+The original logic will use "typedef vector int t;" to judge
+whether <altivec.h> is needed. altivec.h contains the following
+statement:
+
+ #if !defined(__APPLE_ALTIVEC__)
+ #define vector __vector
+ #define pixel __pixel
+ #define bool 
+ #endif
+
+In gcc-4.3.3, __APPLE_ALTIVEC__ is not defined by compiler, neither
+as vector, pixel, and bool. In order to make "typedef vector int t;"
+pass the compilation, we need to include altivec.h.
+
+However in gcc-4.5.0, __APPLE_ALTIVEC__ is defined by compiler,
+so as vector, pixel, and bool. We could not judge whether
+altivec.h is needed by "typedef vector int t;".
+Here we include another statement "int tmp = __CR6_EQ;", in
+which __CR6_EQ is defined in altivec.h.
