And this is as it's supposed to be. 32-bit architectures are usually
ILP32 (ints, longs and pointers are 32 bits) whereas 64-bit
architectures are generally LP64 (longs and pointers are 64 bits but
ints are *not*).
I'm sure you could search for reasons why this is but this is how it
is.
Have a nice day,
