[PHP4BETA] Configuration changes

One thing that has been bugging me for a while is that many of the extensions do not cause a fatal error if a component isn't found. If someone does: --with-foo and the config.m4 rules for the foo extension determine that there is something missing it has to spew an error and make the ./configure fail instead of just turning that option off. It causes too much confusion. I am going to start fixing this in various modules, but keep it in mind for new stuff. -Rasmus -- PHP 4 Beta
