My further mdct optimizations (which patch I have not posted since it 
shouldn't be controversial) depends on split-radix. Merging mdct reorder 
with mdct post-rotation is better than merging it with windowing. Yes, 
post-rotation and windowing could also be merged (if you have enough 
registers; maybe not on x86_32), but that would be even more complex than 
my previous windowing patch.
