did not work in my computer (return always 0), so i changed them for:
I observe the same here, and that's why I wonder if the changes Ignacio proposed made it into the cvs tree? I want to fix these problems, and wonder if I have to patch a HEAD now. Or did you find that these fixes should better not be applied?
