So when checking/building sse code we have three possibilities: 1 Old compiler, throws an error when using -msse* 2 New compiler, user disables sse* (-mno-sse*) 3 New compiler, user doesn't disable sse The original code, added code for #1 but not #2. Later on we patched around the lack of handling #2 by wrapping the code in __SSE4_1__. Yet it lead to a missing/undefined symbol in case of #1 or #2, which might cause an issue for #2 when using the i965 driver. A bit later we "fixed" the undefined symbol by using #1, rather than updating it to handle #2. With this commit we set things straight :) To top it all up, conventions state that in case of conflicting (-enable-foo -disable-foo) options, the latter one takes precedence. Thus we need to make sure to prepend -msse4.1 to CFLAGS in our test. v2: Clean the #includes. Suggested by Ilia, Matt & Siavash.
