Inspired by your comment, I installed 4.1.1 and did very un-scientific test: dcraw compiled [1] with gcc 3.4.5 and 4.1.1. Then convert one raw picture with it: time dcraw-3 -w test.CR2 real 0m10.338s user 0m9.969s sys 0m0.332s time dcraw-4 -w test.CR2 real 0m9.141s user 0m8.849s sys 0m0.292s This is pretty good, and that was only the dcraw, all libraries are still done by gcc 3.4.x.
