Confirmed: 
----------------- 
struct A { 
    A & foo() { return *this; }; 
    A & operator = (const A&) { return foo(); }; 
}; 
----------------- 
 
g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -Weffc++ -c x.cc 
x.cc: In member function `A& A::operator=(const A&)': 
x.cc:3: warning: `operator=' should return a reference to `*this' 
 
This enhancement is rather hard to do, though, since we need to 
track variable values across inlining boundaries.
