Hi Stale, Thanks for the response, I tried grouping the typedef with commas however I received a parser error. I had hoped this would be possible, all the documentation points toward this being possible. My project is rather large, is it possible to zip up the eclipse project and attach it to a post, or to send it to you? Otherwise I will create a "small" test to reproduce, and post that!
