As I added these flags I suppose I should give my blessing to remove them. Frankly, I added them as being matlab compatible and they seemed to make sense to help find over/underflows in algorithms.

They force the use of global flags in the saturated integer math implementations, which is ugly, problematic with possible threading, and probably slows things down somewhat. Does anyone rely on these? Is it OK if we remove them, too?Fine with me :-)
If matlab gets rid of them, presumely for reasons of speed, I suppose the advantages of having them comes down purely to finding under/overflows..... I'd say drop them in that case
