+Subject: [PATCH] SIMD: disable compile time checks
+
+SSE4.1 support is checked at runtime, so compile time checks are
+redundant at best and harmful when compiling for a different machine.
+
+Further more, a logic error prevented the use of SSE4.1 on systems with
+any version of AVX available. This is fixed now.
