[Bug c++/30854] New: [4.3 Regression] Wrong number of arguments printed for constructor

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

On mainline we get a wrong diagnostic for the follwoing code snippet:

================
struct A
{
  A();
};

A a = -A();
================

bug.cc:6: error: no match for 'operator-' in '-A(0u)'

Note, that the constructor has no arguments, but 'A(0u)' is printed
in the error message. This gets even more confusing if you add a
constructor A(unsigned) to A.
