>Description:

  g++ reports an error when encountering a construct 
of the form 'struct anon;'.
  On the program given as an example the error message is:
$ g++ -c foo.cpp
foo.cpp: In function `int main()':
foo.cpp:28: `struct anon_struct2' has no member named `a'
foo.cpp:29: `struct anon_struct2' has no member named `b'

   The example program compiles fine with gcc. It could 
easily be adapted to test both anonymous struct and union 
support both in C and C++.
>How-To-Repeat:
Compile the following file:

struct nested {
    int a;
    int b;
};

struct anon_struct1 {
  struct {
    int a;
    int b;
  };
  int c;
};

struct anon_struct2 {
  struct nested;
  int c;
};

int main()
{
  struct anon_struct1 v1;
  struct anon_struct2 v2;

  v1.a=1;
  v1.b=2;
  v1.c=3;

  v2.a=1;
  v2.b=2;
  v2.c=3;

  return 0;
}
