I advised somebody something similar to that, telling him (like I learned
from the FAQ) that weird machines have weird pointers, that (char*)0 and
0L might have different binary representations and the like. His response
to this was:
	"I claim there are no machines like this"
What do you gurus say about this? How about an example of a machine or OS
where this is true?
