Core extension versions

Hi, as part of the extension version check on PECL it turned out, that the extensions in the core are almost completely out of track with their versions, not even to talk about version macros names. That regards to exts imported from PECL as well as to the exts never been in PECL. Here are a few examples of zend_module_entry version strings: ext/simplexml "0.1" ext/bz2 NO_VERSION_YET (== NULL) but was PECL 1.0 in 2003 ext/pdo "1.0.4dev" whereby it was PECL 1.0.3 in 2006 and the winner might be that from ext/tokenizer "0.1", /* Replace with version number for your extension */ as if it were just generated :) Only a few extensions, just to name some - zip, dom, oci8, track the version number. Actually that doesn't look solid for the extensions being in the core for years. And while that's a minor issue, it doesn't really smell good. So, do we wanna do something about it? Regards Anatol
