[Bug c++/21353] New: rvalues should not be allowed to be default values for non const references in class functions.

["s_siddharth_reddy at yahoo dot com" <gcc-bugzilla at gcc dot gnu dot org>]

works as expected on : gcc 2.95, freebsd/linux
does not work as expected on: gcc 3.4.2, freebsd/linux

//non-const references to temp values should be disallowed
--------------
//the code
enum X{ a, b, c };
class C
{
public:
       void func( X & ref = a ) //illegal - should not compile.
       { }
};
int main( )
{ }

//compile with gcc 2.95
$g++ test2.cpp
test2.cpp:7: invalid type `X' for default argument to `X &'

//compile with gcc 3.4.2
$g++3 test2.cpp
$ 
----------------

this problem does not exist for functions in global scope.
