To whoever updates the GD config docs, please do not use the term "built-in" as it is not built-in but rather a php version of GD is bundled.  Windows has and still includes the GD dll's in the download.

Information should include what version of GD is bundled, what differences occur from the boutell version for that given version, and that it is <emphasis>strongly</emphasis> suggested to use the bundled version.

Simply --with-gd or --enable-gd will use the bundled version.  I'm not sure the best way to describe that --with-gd does not look for a local copy of GD on the system in {PREFIX} like most options do and like --with-gd used to do before PHP 4.3.0.

Anyway, this is a tricky one so please do some research before committing :)

The configure options for GD is available at http://www.php.net/manual/en/ref.image.php. Anyway the information needs to be updated in the points Philip mentionded.

The infos from http://www.php.net/manual/en/install.configure.php#install.configure.options.graphics will be deleted soon.

FWIW: php.net/image does mention it's bundled and how to install, as Friedhelm mentioned.  I added the windows dll info there.

Additional information does not yet exist but most likely will eventually although it's not _that_ important.

Regarding the outdated install.configure.xml, I have no comments other than Friedhelm is working on all the install.* stuff so it's being worked on.

I think everything is explained now.
So, closing.
