Yes, this is completely normal if you use IEEE floating point, due to decimal <-> binary conversion and other accumulating rounding errors. In other words, floating point calculations will almost never be exact... This is not a gcc problem. In fact, I can even reproduce your output under Windows using a Microsoft C compiler! :)
