Mostly, several functions that take pointers as arguments, almost always char * pointers, had those pointers qualified with "const". Those that returned pointers to previously const-qualified arguments had their return values qualified as const. Some structure members were qualified as const to retain that attribute from the variables from which they were assigned. The macro DE_CONST was added to isc/util.h to deal with a handful of very special places where something is qualified as const but really needs to have its const qualifier removed. Also cleaned up a few places where variable names clashed with reserved identifiers. (Which mostly works fine, but strictly speaking is undefined by the standard.) Minor other ISC style cleanups.
