Sorry, what do you mean by "not native" ?
sizeof(int) != sizeof(void *) or something else?
On Linux that is not true! From wikipedia on '64-bit':
Many 64-bit compilers today use the LP64 model (including Solaris, AIX,
HP, Linux, Mac OS X, and IBM z/OS native compilers). Microsoft's VC++
compiler uses the LLP64 model.
So on Linux: sizeof(long) == sizeof(void *), that's why the kernel uses
'long' all over the place instead of 'int'.
