We have decided to go PHP 5. Thanks for your input. The exact steps we
will do are still under discussion amongst the phpMyAdmin team and I'll
discuss it also with other members of the "Go PHP5" coalition.
We feel that the cycle where PHP dev team still has to support PHP 4
because providers still use it (because PHP dev team still supports it
...) needs to be broken.
