Well, it's sizeof(pointer) so either 4 or 8, but still,
what Markus proposes here is _wrong_.

Markus, do you know the script probably has a lower
style conversion defect introduction rate than you do
when doing these mechanical things.

Please use it to verify what you are doing before
submitting more defective patches.

Excuses and apologies aren't good enough at this point.
