Come *ON*, why is this accepted? I remember not so very long ago people were
flaming Microsoft for doing this on the Macintosh, which led to Microsoft
applications not working on >1MB machines after the extra bits started getting

Not to mention that making assumptions about pointer formats is dangerous in
and of itself. Certainly you can't *use* such pointers without stripping them,
which adds overhead to every memory reference. And (per recent discussions
in comp.std.c) there are architectures out there that won't even let you load
them into an address register.
