>Description:
Given the following program:

arta:~/c/proba$ cat ptr2mem.cc
struct a
{
  int f() const;
};


int
a::f() const
{
  int (a::* b)() const = &a::f;
}
arta:~/c/proba$ g++3 -v
Reading specs from /gml/shared/gcc-3.2.3/lib/gcc-lib/i686-pc-linux-gnu/3.2.3/specs
Configured with: ../gcc-3.2.3/configure --prefix=/gml/shared/gcc-3.2.3
Thread model: posix
gcc version 3.2.3
arta:~/c/proba$ g++3 ptr2mem.cc
ptr2mem.cc: In member function `int a::f() const':
ptr2mem.cc:10: ISO C++ forbids taking the address of an unqualified non-static 
   member function to form a pointer to member function.  Say `&const a::f'
zsh: exit 1     g++3 ptr2mem.cc
arta:~/c/proba$

I think &f should be enough, but &const a::f
(as suggested by the diagnostics) is refused by g++
(I think rightly so).

(&a::f is accepted.)
