Nios Examples get many warnings on compile

Thanks for the 2 replys. They were both useful. The issue I have is that there are 350 warnings with a small NiosII cpu, now when I add in my own IP blocks to the design I will have to go through all 350+ warnings and try to figure out which ones are related to the NiosII (which I have no controlver) and which ones are related to my IP blocks. This will need to be done every single time I compile my design. I would have thought there would have been an easy way to set thing up such that the Nios cpu doesn't create any warnings (or very few).
