static member function erroneously thought to be ambiguous...

...when the class that defines the static function appears multiple
times as a base class of the caller.  I seem to be unable to attach a
file and still have the message delivered, so please find the test
case below.

I am using egcs-2.90.29 980515 (egcs-1.0.3 release).

Couldn't find mention of this bug on the website.  So it may be a bug
in the latest release (which is why I'm reporting it).  I'll test it
with the latest release at my earliest opportunity.

  ...begin test case...
// demonstration of a bug in egcs where static methods are considered
ambiguous
// when the class that defines them appears as a base multiple times
in the callers class

class base
  {
    public:
      static int a_static_method() { return 3; }
        // should be accessible to anyone as |base::a_static_method()|
  };

int
non_member_test()
  {
    return base::a_static_method();
      // Legal
  }

class not_derived
  {
    public:

      int
      test_method()
        {
          return base::a_static_method();
            // Legal
        }
  };



class X : public base {  };
class Y : public base {  };

class derived : public X, public Y
  {
    public:

      int
      test_method()
        {
          return base::a_static_method();
            // Legal and unambiguous (only because it's static), but
            //   erroneously flagged as ambiguous by egcs

 // test.cpp: In method `int derived::test_method()':
 // test.cpp:42: type `base' is ambiguous baseclass of `derived'
        }

  };

  ...end test case...

Hope this helps,
