php4 port build changes

[John Brooks]

Apparently a few days ago the entire build process for
php4 has been changed. But documentation on how to select
extensions is nowhere to be found (at least I couldn't find
it). The end result is that basic items like session support,
mysql support, etc will break if you upgrade. 

Anybody know where the docs are on how to activate php
extensions?
