If you run a 32-bit app on a 64-bit system, it was still compiled as a
32-bit app.

Why do you want to know the word size of the kernel?

Because I want to check if installed/running binaries are well fited.
It's perfectly legal to run 32 bits on a 64 bits os, but in some case
my program load external dll or external program load some of my libs.
And mixed 32/64 bits dll is a source of errors. So I prefer warm user
that installed version is not the right. On same spirit, it's not good
to run X86 binaries on itatium because emulation has a big cost.
