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! :)
