是否有可能编译pre-ANSI（K＆安培; R式）C code用Visual C ++？

问题描述：

我们有一些旧的C code。与pre-ANSI（K＆安培; R样式）函数声明。例如：

We have some old C code with pre-ANSI (K&R-style) function declarations. For example:

int foo(x, y)
double x, y;
{
    /* do some stuff */
}

有没有编译器开关，以便在Visual C ++ 2008支持这个功能？

Is there a compiler switch to enable support for this in Visual C++ 2008?

答

为了得到这个编译把code在.c文件与一个.cpp。这指示的Visual Studio编译code为C，而不是C ++

In order to get this to compile put the code in a .c file vs. a .cpp. This instructs Visual Studio to compile the code as C instead of C++
