>Description:
Hello,

thank you for your efforts to support free software. As you might guess,
I think I have found a bug in g++ 3.2.1. The compilation of the following 
(to the best od my knowledge correct) code exits with an error.
(icc and the online comeau compiler accept it.)

+++++++++++++ begin code +++++++++++++++++

struct foo {
  static int bar(...);
  static int const RET = sizeof(bar(0));
};

int main() 
{ return 0; }

+++++++++++++  end code  +++++++++++++++++

When the code is compiled without any command line flags, I get the
following error message:
g++bug.cpp:5: invalid use of undefined type `struct foo'
g++bug.cpp:3: forward declaration of `struct foo'

The error disappears, if bar is not a member of foo. Calling bar(0) works
fine, too.

    Duplicate of 9259. The problem doesn't have to do with the
    ellipsis, though, it also fails for any other function.
