Hi Martin,

Your email is hardly readable, because
  1. it is a HTML email,
  2. when viewing it as plain text - which is the only secure way to read mail
     [1] - the cited text is not indented.
Please configure your mailer for plain-text mail [2], if you want to continue
to write to mailing lists. And indent or otherwise mark cited text.

What does this program print?

And this program proves nothing, because you cast away the upper 32 bits
of 'ret' before printing.
