pro-rsoft: Right now only cg and (presumably) ode work with 64 bit - that thirdparty file contains ffmpeg and OpenAL as well because whilst I compiled them and attempted to get them working it proved to be too complicated for the amount of time I had. (Though the problems themselves are probably quite simple - its the matter of understanding what is going on that is the time consuming bit.)
At some point I might find the time to have another go at this and get them working, but I don’t actually need either of them yet and so am in no hurry I’m afraid. Apologies for being fundamentally self centred;-) But right now it makes sense to omit them, as that way people will not try and compile them and suffer the inevitable failure.
