 Priority:  normal   |   Milestone:  2.5.2                                 
Component:  General  |     Version:  2.5.1                                 
 Severity:  normal   |    Keywords:  register_activation_hook plugin global

 When the function called by register_activation_hook is requires variables
 that are declared in the main code of a plugin, they are not available as
 globals, however wordpress vars such as $wpdb are. For example:

 {{{

 $my_plugin_some_var = "foo";

 register_activation_hook(__FILE__, 'my_install_func');

 function my_install_func() {

 global $wpdb; // wordpress var, this will be fine
 global $my_plugin_some_var; // this will not work, the var will have to be
 re-declared here

 ....

 }

 }}}

 This is particularly frustrating for plugins that create tables in the
 database and wish to store the table name in a variable for access in
 other functions that access data in those tables.
