I just thought I'd try Jim's OneWire library and got the following errors when the Arduino environment (11) starts up:
I don't think Jim's original library is usable in anything but Arduino-007. It had to be updated to work with changes in the header files in later Arduino releases, as you can see from your compile errors. I didn't start working with it until Arduino-010, myself, and have only tried using the most recently updated versions. At this point, the most recent update that I'm aware of is mine, which is referenced on the OneWire page in the playground; I would recommend you use that.
