Comment (by Mr Pete):

 Ummm... that can't possibly fix it ;)

 Look at schema.php -- It grabs a role object, then uses it to insert a
 bunch of capabilities.

 In PHP5, it automatically grabs a reference to the original, and all is
 well. Doesn't matter whether you "&" or not.

 In PHP4, unless you "&" both the declaration AND use, it grabs a COPY of
 the object. So, the inserted capabilities never make it into the original
 object instantiation!

 In PHP4, declaring the function with "&" means it is capable of returning
 a reference. Using with "&" means it actually grabs a reference. Eliminate
 either one, or both, and you get a copy.

 Thus, to code compatibly for PHP4 and PHP5, you have to use "&" in both
 declaration and use.
