Architecture: i686

>Description:
	A member function of a class is invoked through a function pointer from within a static member
	function of the same class. This is a valid C++ construct, however, the compiler flags it as an
	error.

>How-To-Repeat:
Compile this program:

/* GCC 3.0.4 bug demonstration program */

class A
{
  void f1(void);
  static void f2(A &c);
};

void A::f1(void) {}

void A::f2(A &c)
{
  void (A::*pf)(void);
  pf = &A::f1;
  c.*pf();
}



Compiler output:
bugdemo.cxx: In static member function `static void A::f2(A&)':
bugdemo.cxx:15: pointer to member function called, but not in class scope
