+Subject: [PATCH] Detect SSE2 support
+
+Compilation on an older 32-bit Athlon XP chip fails with the error
+"./Utils/AEUtil.h:50:12: error: '__m128i' does not name a type"
+This is because the __m128i type is only available on SSE2 platforms.
+Modify the preprocessor logic to detect SSE and SSE2 support separately.
+
+The "emmintrin.h" header should only be included on SSE2 platforms as
+well.
