You should probably say ix86 Linux. On Alpha Linux and IA-64 Linux,
these numbers are different.

Also, these are not a property of the OS alone. It is a combination
of the compiler and the OS.

Specifically, you can have a different compiler which uses a
different data model that runs on ix86 Linux. Also, the same compiler
can generate different code, based on a command line switch.

In other words, assuming things about sizes of various data types is
bad programming. That is why the sizeof operator exists.
