	Speed shouldn't matter a great deal since these tables are only 
computed at codec init. However, it may be useful to create an 
implementation that does not rely on the math library. I suspect that's 
why FAAD2 hard-coded the tables-- to target platforms with no math 
library. A quick grep through FAAD2 source for "math.h" appears to 
confirm this (if fixed point is selected, don't include math.h).

	Anyway, I guess we will leave it up to Oded The Implementor to decide 
which version to use.

	Thanks...
