VC6提示 error C2061: syntax error : identifier 'THIS_FILE' 错误的解决办法

今天在编译一段以前写的代码时候，遇到了这样的错误

双击第一个错误，居然跳转到了完全陌生的系统头文件

\microsoft visual studio\vc98\include\new(35)

中。开始怀疑是新老SDK混合引起的冲突，修改了几下参数，无果，只好向GOOGLE请教了。搜索一番之后很快明白了问题的所在，引起错误代码是这样的

 

#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif
//
//blah blah, lots of codes here
// 





#include <vector>
using namespace std;

 

由于new已经被宏定义为DEBUG_NEW，所以在<vector>中包含的<new>中如下代码就出问题了：

void *__cdecl operator new(size_t) _THROW1(std::bad_alloc);

解决方法也很简单，把

#include <vector>
using namespace std;

两行代码，移到最前面即可！
