I'll answer although I don't know much about gcc4, so this might not be 100%... gcc4 is a big change (under the hood) from gcc3 with the optimisation logic totally rewritten. Make sure you try and build with full optimisation set (-O3 I guess). The new sigmoid version uses SSE4 I think, which is supported in gcc4, this code isn't checked in yet. I think you are a bit confused about mixing gcc3 and 4 (or you've confused me), we only build the one .exe and either compiler will work fine with the existing gtk dlls.
