Matt, basically that #define allowed Microchip to move from the older 
method of using & (AND) to combine Constants when making up function 
parameters - a method I almost never saw in use :) - to the more common 
! (OR).

But, in order to do that, they had to almost duplicate their include 
files etc, and the USE_OR_MASKS is used to pick one of the 2 method 
(let's call it retro-compatibility)
