>Description:
	The new C++ parser is not able to pinpoint the actual problem in
	the following piece of code, while GCC 3.3 has no problem doing so;
	GCC 3.3 issued a single error, while the new C++ parser prints a
	cascade of 10 error messages.

static void InstantiateConstraint(const float&, unsigned,
                                  void(*AddFunction)(const TYPE&,bool&,
                                                     char*, char*,
                                                     unsigned*));

>How-To-Repeat:
	% g++3.3 x.cc
	x.cc:2: parse error before `&' token

	% gccvs x.cc
	x.cc:1: error: variable or field `InstantiateConstraint' declared void
	x.cc:1: error: expected primary-expression
	x.cc:1: error: expected primary-expression
	x.cc:2: error: `AddFunction' was not declared in this scope
	x.cc:2: error: expected primary-expression
	x.cc:2: error: expected primary-expression
 	x.cc:3: error: expected primary-expression
	x.cc:3: error: expected primary-expression
	x.cc:4: error: expected primary-expression
	x.cc:4: error: initializer list being treated as compound expression
