Right, much simpler :)

Don't think so, usual ones should cover our current needs, I don't have 
any #ifdef EFOO in the BeOS code, didn't see any for other platforms.
Except an unused ENODATA in libavutil/internal.h.
Who did this anyway ? It's nowhere used, and so should be removed.

Righto, I was still asleep :)

Ok I'll try that and see what it gives.
It seems even simpler in the end.
