When running PHP 4.0RC1 under Roxen 2.0.46, it never chdir's to the directory of the script, instead it stays in /usr/local/roxen.

This really screws up with relative paths for include() and fopen(). You could of course, chdir yourself in every document, but this is definitely not the behaviour I've seen in Apache. 

Script to reproduce problem. It should show the files /usr/local/roxen rather then the scripts directory:

$handle = opendir('.');
while ($file = readdir($handle)) {
  print ("$file\n");
}
closedir($handle);

configured with:
./configure  --with-roxen=/usr/local/roxen/server --with-mysql --with-xml

php.ini: 
only difference is include_path has "."
