One option is not to support 2.2 > which the poll check in so far seems to imply at least with making things unsupported in the RELEASE is not an option in my opinion, unless there are strong technical motivations against it, and this is not the case. I browsed through the various files involved in the poll change and could not find any way the preprocessor could tell the difference. So I have used a new macro, USE_POLL, which must be defined in sound.h by users who want to compile this code on 3.0. Fortunately it is used only in one function and one other place, so its removal should be fine when this code finally finds its way into 2.2.X I am finishing the modifications and will put a new snap of the code on my web server quite soon.
