I meant a configure or cmake switch for the project (and #ifdefed explicit SSE code), not a global compiler switch.

-mno-sse4 is the way to go (or a proper -march). :+1:

@trevorm:
A new build where I tried to disable SSE4 with CFLAGS=-mno-sse4 CCFLAGS=-mno-sse4 in libpng.

It seems to run ok on my imac8,1 which has SSE4.1 (intel E8235) where an imac7,1 does not (intel T7700).
