Subject: [Bug c++/17634] New: default arguments not permitted in typedef's
X-Bugzilla-Reason: CC
X-SW-Source: 2004-09/txt/msg02758.txt.bz2
List-Id: <gcc-bugs.sourceware.org>

The following used to compile in gcc 3.3:
	$ cat foo.cc
	typedef void (*Function)(int n = 1);
	$ g++ -c foo.cc
	$ 

It doesn't compile anymore in gcc 3.4:
	$ cat foo.cc
	typedef void (*Function)(int n = 1);
	$ g++ -c foo.cc
	foo.cc:1: error:
	default arguments are only permitted for function parameters
	$ 


Although I'm not sure this is legal C++, I've opened a bug report because the
following does work with gcc 3.4, which seems inconsistent:
	$ cat foo.cc
	struct MyClass {
	    typedef void (MyClass::*Function)(int n = 1);
	};
	$ g++ -c foo.cc
	$
