From: Kurt Taylor <krtaylor@us.ibm.com>

Attached is a patch for adding the llGetSunDirection functionality. It was implemented by adding a parameter to estate settings for storing the sun position. The sun position is calculated and stored via the sun module everytime the client's sun position is updated. It was tested with several different srcipts on Linux and Windows
