有一个C++模板，ansiC++的，请帮忙看看VC++怎么编译
是一个GsTL（http://gstl.sourceforge.net/）的模板，用于科学计算，readme里面说支持ansiC++的都能编译，不过我用vc2008却不行，说是：
错误4error C3083: “value_type”:“::”左侧的符号必须是一种类型
弄不清怎么回事，请高手帮帮忙。

[解决办法]
Neighborhood应该是一个class，但没有找到它的定义，因此编译器不认识了
把Neighborhood声明的头文件包含进来
[解决办法]
看看Neighborhood是在哪声明的
[解决办法]
Neighborhood是模板参数啊，传进去的实际类是什么？
[解决办法]
额 neighborhood里面没有一个value_type的定义。
