This works in Visual C++, but not with the Sun Compiler.
Stack<Tree<int>> stack; // (Line 40)
line 40: Error: "," expected instead of ">>".
line 40: Error: Illegal value for template paramter.
line 40: Error: "," expected instead of ";".
line 40: Error: Illegal value for template paramter.
What is wrong with this declaration? Thanks.
