 The problem can be demonstrated with the following (illegal) code snippet:
 
 --------------------------snip here-----------------------------
 template <class T> struct A
 {
     void foo() { bar(T); }
     void bar();
 }
 
 typedef int INT;
 --------------------------snip here-----------------------------
 
 With mainline I get the following error message:
 
 PR4707.cc: In member function `void A<T>::foo()':
 PR4707.cc:3: error: parse error before `typedef'
 PR4707.cc: At global scope:
 PR4707.cc:7: error: extraneous `int' ignored
 PR4707.cc:7: error: template declaration of `typedef struct A<T> INT'
 
 There are two things correct about the error message:
 * The bug is in the member function `void A<T>::foo()'.
 * It is in line 3 (you cannot use the template parameter T like this).
 
 The rest is bogus:
 * The parse error happens before ")" and not before the "typedef"
   which comes after the end of the whole struct. You can actually
   place as many members between "foo" and the end of the struct as you
   want - the parser complains about the typedef.
 * The last three lines of the error message are nonsense.
 
 Hopefully, this gets fixed with the new parser.

 The real error of course is the lack of a semicolon after the struct 
 declaration. This brings the typedef into the trouble with the class. If I 
 add the semicolon, I get a much more reasonable message:
 
 tmp/g> /home/bangerth/bin/gcc-3.3-pre/bin/c++ -c x.cc
 x.cc: In member function `void A<T>::foo()':
 x.cc:3: error: parse error before `;' token
