[Bug c++/13113] New: [3.4 regression] Nice warning about &(X::m) lost

[Bug c++/13113] New: [3.4 regression] Nice warning about &(X::m) lost

[bangerth at dealii dot org]

Sometime in the 3.2 series, a nice warning was introduced for
code like this:
--------------------
struct A {
    int f();
};

int (A::*p)() = &(A::f);
---------------------

g/x> /home/bangerth/bin/gcc-3.2.3/bin/c++ -c x.cc
x.cc:5: parenthesis around 'A::f()' cannot be used to form a
   pointer-to-member-function

This got lost with the new parser, which now says

g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c x.cc
x.cc:5: error: invalid use of non-static member function `int A::f()'

I can confirm this, I had meant to file this on after closing a different bug last night after seeing it 
did not ICE any more.

:-(  That warning was part of the job of resolve_offset_xxx -- which
used to ICE on such code.  
I wish the cp/error.c display 'A::f' instead of the silly 'A::f()',
but it is something that seemseasier to do with the new
pretty-printer.
