Nice cast. This _will_ cause a hard crash on a dereference attempt on
most machines. Maybe that's intended, though...
(Well, it might even work on '86 style machines, though, as these are
still 8-bit based yet.)

You're _certain_ that the compiler "understands" the conditional
construct?
I'd assume that it doesn't even try to evaluate it, but just find a
type definition that may not comply for some of the supported
architectures, which is the condition that triggers the warning.

Don't know - just can assume that it's caused by overblown expectations
as to the intelligence of a simple code converter, aka compiler.
