The diagnostic for the following invalid code snippet degraded in GCC 3.4.0:

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

Since GCC 3.4.0 we get:

bug.cc:3: error: the default argument for parameter 0 of 'A::A(const A&)' has
not yet been parsed

But before we got the much clearer diagnostic (although it was just a warning):

bug.cc:3: warning: circular dependency in default args of `A::A(const A&)'

In addition, the counting of the parameters should start with 1.
