Hi all,
since I missed the commit and this is news to me - maybe one could add a word
why this _is_ news and actually noteworthy?
IIRC, there was something that absent dummy arguments where marked by 0L,
hence one could not pass a NULL pointer as it would be seen as "absent" not as
"present with value 0". If that's the one, mentioning it might certainly help
an unaware reader.
Just a thought.
Daniel
