No, because 32bit code will tell the datatype size and i think pointer
variable depends on architecture.
So 64 bit processor needs 64 address line to point the data location. So
pointer variable needs to be 8 byte.

Please don't top post and please use the new list address, ok? :)

IMO, I second your opinion. And as addition, I think it's worth to
check /proc/cpuinfo too  in "address sizes" field

NB: I was thinking, if in x64, it is operating in full 32 bit mode
(not hybrid one), it is supposed to yield 32 bit address too, right?

Why not simply use CPUID ?
