Apparently, most of the extensions PHP ships with seem to
work out of the box. I'm under the impression that almost no
changes are required, unless you directly manipulate objects.
That brings up the question -- do we have some documentation
for extension authors which covers necessary changes.

There is an important difference regarding developer
awareness:
No. of args change: The compiler will always bail out.
Developer knows: Aha, I need to fix something.
Signedness change: The compiler might issue a warning or not.
Developer knows: Usually nothing.
There are so many signedness issues in ext/standard alone,
that I would not want to run with such warnings enabled.
