"the program dosn't do, what I expect"
 is not a bug. A bug is "the program doesn't do what the
programmer expected". If 'man' program doesn't create a
little man to help you with your C code, it's not the
program's fault :)

And no, it cannot work the way you proposed, because there's
no way to discover what that "other" variable, that $foo is
linked to, was in the first place. It's located in another
symbol table, which is not available in that function. But
if you don't really need unset (which wipes the variable
completely), you could just use something like $foo=false,
which does work on references perfectly.

My problem is, that old PHP3 scripts won´t work with PHP4, if they use such a 

And it is a bug in the meaning of "the program dosn't do, what I expect". Ok, the bug 
is documented, but look at the ERROR-ID #8972 for a case, that makes a much more 
surprising and unexpected effect.

Why can't PHP just overwrite the value with the value "UNSET" in the case of unsetting 
a reference - instead of removing the reference?

So, what's the problem with your latest code? I do not see any.

Bug or feature. Thats the question. :)

Sorry, it IS a bug. 4 people have mentioned this and I found now a
test case, where no workarround exists.

But I found another problem in this context. Will make a new ticket.

This isn't a bug, but a feature =)

If you use GLOBAL within a function it creates a reference to the orignal variabele, 
this reference is local to the function. SO if you unset() this variabele, you're only 
unsetting the reference (and thus not the GLOBAL variabele). This is documented 
behavior (from the unset() manual page):

   If a globalized variable is unset() inside of a function, only the
   local variable is destroyed. The variable in the calling environment
   will retain the same value as before unset() was called.
