 In summary, WordPress can't be used in a single source installation.

 To achieve this, I'm using a technique which involves having WP in a
 master directory, plus a "phantom" directory for each different blog -
 where wp-config.php resides, and the other WP files are symlinks to the
 master directory's contents.  I thus, for each blog, set the Apache
 DocumentRoot to the blog's phantom directory (which contains that blog's
 wp-config.php) rather than to the master directory.

 This would work okay, except for the fact that, on wp-blog-header.php, `if
 ( !file_exists( dirname(__FILE__) . '/wp-config.php') ) {` does not work,
 because __FILE__ points to the *real* wp-blog-header.php instead of to the
 wp-blog-header.php on the phantom directory.  Of course, this results in
 wp-config.php "not existing".

 Since, for all general executions of the blog engine, dirname(__FILE__) in
 wp_blog_header.php should equal the results of getcwd(), I'm changing
 this.  Attached is the patch that performs this fix on WordPress 2.0.3
 (plus nonces fixes).
