conflict with PHP 5.0.5

When I installed this module and tried to go to phpchatroom settings, I got the following error:

Fatal error: Only variables can be passed by reference in line 60 /modules/phpfreechat/phpfreechat.inc

Some searching pointed to this being a problem with PHP 5.0.5 (see: http://drupal.org/node/32881 )

I was able to get this to work by changing this:

function _phpfreechat_check_files() {
  // Create data folders:
  // PS: I had to pass first parameter as a variable since file_check_directory
  // accepts only variables since it references the first parameter
  return (
    file_check_directory(file_directory_path(), FILE_CREATE_DIRECTORY, 'op')
    && file_check_directory($f = PHPFREECHAT_DATA_DIR, FILE_CREATE_DIRECTORY, 'op')
    && file_check_directory($f = PHPFREECHAT_PRIVATE_DIR, FILE_CREATE_DIRECTORY, 'op')
    && file_check_directory($f = PHPFREECHAT_PUBLIC_DIR, FILE_CREATE_DIRECTORY, 'op'));
}

to this:

function _phpfreechat_check_files() {
  // Create data folders:
  // PS: I had to pass first parameter as a variable since file_check_directory
  // accepts only variables since it references the first parameter
  $chat_path = file_directory_path();  
  return (
    file_check_directory($chat_path, FILE_CREATE_DIRECTORY, 'op')
    && file_check_directory($f = PHPFREECHAT_DATA_DIR, FILE_CREATE_DIRECTORY, 'op')
    && file_check_directory($f = PHPFREECHAT_PRIVATE_DIR, FILE_CREATE_DIRECTORY, 'op')
    && file_check_directory($f = PHPFREECHAT_PUBLIC_DIR, FILE_CREATE_DIRECTORY, 'op'));
}

Not sure if that's a good solution, but thought I'd at least point it out.
