SSE chunk genneration doesn't seem to work on my windows install

[rs2k]

I can get the SSE4 to work on 64 windows and linux only if I'm running an Intel processor. My current AMD chips don't want to run it. Here's an example of what I get.

Code:

[00:24:43] cWorld::cWorld(world)
[00:24:43] Seed: 1015577794
[00:24:43] Loading spawn area
[00:24:43] Created new chunk! 68 -304
[00:24:43] Created new layer 2 -10 (total layers 1)
Illegal instruction (core dumped)

Runs just fine on my Intel's though. :/


Is there a way to only enable SSE4 if the current CPU is known to support SSE4.1? My newest AMD chip is a Phenom II x4 955, and it doesn't have SSE4.1 support, only SSE4A support.
