I don't think this binary incompatibility is so great that we need to bump the middle number. If we do that then we should probably think about other changes as well and maybe even creating a cygwin2.dll. Anyway, my initial thought that my changes would speed things up may have been too optimistic. The DLL that I've created is 30K larger than the previous version and I'm not sure why. I'm investigating now. cgf
