 Hi

 I've noticed a number of plugins hardcoding their plugin directories, and
 I think I see why. If you develop a theme, and that theme depends on
 plugins, it's tempting to bundle the plugins along with the theme files
 (i.e. all in wp-content/themes/mytheme).

 Then, to allow Wordpress to use these plugins, it's common to symlink wp-
 content/plugins to wp-content/themes/mytheme/plugins, or somesuch.

 That means that plugins using plugin_basename(__FILE__) will break, as the
 WP_PLUGIN_DIR path will not be removed from the full  returned path.

 I've written a patch for wp-includes/default-constants.php that will
 detect if the plugins directory is a symlink, and if so will use the
 appropriate correct path as part of the constant, thereby ensuring all
 paths calculated by plugins are correct based on this constant.
