No, OS X does not support 64-bit pointers in any of the system software
yet. (I'm not sure if some of the compiler flags for 64-bit math make
void* a 64-bit quantity which is then clipped when passed as an
argument to a library, anyone know?) The horizon is very cloudy at
this point. My personal feeling is that there is no way this will be
in 10.4 (OK, maybe the odd library here and there might have a 64-bit
version but certainly not pervasively). I would guess that 10.5 would
have substantial support for 64-bit pointers in all the lower levels
(libmalloc, libc, etc.) but probably not in Cocoa or Carbon. The full
transition will probably take close to 3-5 years.

if not, is that on the horizon?
