Um, I think you are mistaken.
No.
Integer is *always* 32-bits on either
32-bit or 64-bit target platforms.
It *happens* to have 32 bit there. On 16 bit platforms (TP, Delphi 1) it
was 16 bit. I'm not sure when Delphi changed that to 32 bit, perhaps not
before D3.
NativeInt is different sizes on
different target platforms. I think LongWord also varies in size based
on target platform, though not 100% sure on this one.
In Delphi (XE) NativeInt has the CPU register size, assuming that data
and address registers have the same size (i.e. unsegmented pointers).
LongWord still is documented as a fundamental (non-generic) 32 bit type.
