On the mainline I get this:
pr4707.cc: In member function `void A<T>::foo()':
pr4707.cc:3: error: expected primary-expression
pr4707.cc: At global scope:
pr4707.cc:7: error: extraneous `int' ignored
pr4707.cc:7: error: template declaration of `typedef struct A<T> INT'
Is this fixed as it does not complain about a typedef not is not there any more?

gcc 3.4 snapshots seems to be changed a lot in this area.

The current debian gcc snapshot (2003.08.15) returns with a lot of errors to my
code (http://hacks.dlux.hu/gcc-bug/typedefbug.gz), which I don't really
understand. In fact, this does not contain the original error message, but
contains million others.

I can't really decide if this solved the problem or not.

I think the messages are about the best the compiler can do. To explain where they 
come from, remember that a typedef can not only have the form 
  typedef int INT; 
but also this abomination: 
  int typedef INT; 
Now, with a structure, this is legal: 
  struct A { int i; } typedef INT; 
 
The problem comes here: in the reduced testcase, we have a template, not a structure, 
which cannot be typedef'd. Furthernore, since the compiler sees the infix-form of the 
typedef (rather than the usual prefix form), the only thing that can come after the "typedef" 
can be a single name, so that's where the "extraneous `int' ignored" comes from. 
 
Given this strange form of the typedef declaration, I think the compiler can do not better 
than what it is presently giving, so I close the report.
