Fixed for Drupal 6.4

I have, of course tried both of the versions 6.x-1.x-dev and 6.x-1.0 under Drupal 6.4. They were not working at all. Examining the code this was clear, and it is difficult to conceive how it would work under 6.x according to the API docs.. Has anyone tested it under 6.x?

Let's look at some of the stock.module from 6.x-1.x-dev problem lines

Line 100: 'callback arguments' will not work as it has been renamed to 'page arguments' for 6.x. Because of this the Admin settings would not come up.
MENU_LOCAL_TASK is not necessary as it will ignore the 'title' and use "Home" instead. And $title is forgotten to be defined (which is not a Drupal issue).

Line 278:
return array();
for theme registration is wrong for 6.x and will halt all the output. it should be
return array( 'stock_page' => array() );

Line 144:
function stock_form_definition($symbols) {
the actual callback under 6.x is
stock_form_definition($form_state, $symbols) {
so the saved user symbols would not show up in the form, and cause a preg error in bootstrap.inc.

Just discovered:
Line 377:
return _system_update_utf8(array('stock'));
_system_update_utf8() has been discontinued since 5.x
this callback reports a 'necessary' database update that will fail.

I will look into creating a patch.
