g++ 4.0.3 as well as g++-3.4 fails to compile the attached program b.cpp with
the following errors:
b.cpp:12: error: declaration of 'operator-' as non-function
b.cpp:12: error: expected ';' before '<' token
Things become even worse if we make int x; private in class A (see b2.cpp).
g++ 4.0.3 starts complaining:
b2.cpp:12: error: declaration of 'operator-' as non-function
b2.cpp:12: error: expected ';' before '<' token
b2.cpp: In function 'A<n> operator-(const A<n>&, const A<n>&) [with int n =
0]':
b2.cpp:18: instantiated from here
b2.cpp:7: error: 'int A<0>::x' is private
b2.cpp:23: error: within this context
b2.cpp:7: error: 'int A<0>::x' is private
b2.cpp:23: error: within this context
b2.cpp:7: error: 'int A<0>::x' is private
b2.cpp:23: error: within this context
g++ 3.3 compiles both b.cpp and b2.cpp without a single warning. So I believe
this is a regression.
