[Bug c++/24926] New: gcc ignores access level violation: struct variables in anonymous union accessible as public

["gcc at warped-space dot de" <gcc-bugzilla at gcc dot gnu dot org>]

When declaring an anonymous union inside a class,
any variable from an anonymous struct contained in the union is accessible 
like a public member, regardless of the access level of the enclosing union.

Bug does only occur when struct and union are BOTH anonymous.

The following sample code, which violates access level, compiles under gcc
3.3.6, 3.4.5 debian prerelease and gcc 4.0.2.

Expected result: gcc should report access level violation.

---- testcase ----

class foo {
private:
  union {
    struct {
      int should_be_private;
    };
  };
};

int main()
{
  foo test;
  test.should_be_private = 1;
}
