VC++ 标准库链接错误

我在使用 VC++ 编译器时遇到了问题。我已经安装了带有编译器、库和标头的 windows sdk，并尝试编译如下测试程序：

#include <cstdio>
int main(int argc, char* argv[]) {
    printf("%s", "Hello world!");
    return 0;
}

这是我用来编译的命令行脚本：

@echo off
set clpath=C:Program Files (x86)Microsoft Visual Studio 10.0VCbinamd64
set clname=cl.exe
set linkpath=C:Program Files (x86)Microsoft Visual Studio 10.0VCbinamd64
set linkname=link.exe
set libpath=/libpath:"C:Program FilesMicrosoft SDKsWindowsv7.1Lib" /libpath:"C:Program Files (x86)Microsoft Visual Studio 10.0VClib"
set includepath=/I "C:Program FilesMicrosoft SDKsWindowsv7.1Include" /I "C:Program Files (x86)Microsoft Visual Studio 10.0VCinclude"
set subsystem=console
set entry=main
set libfiles=
set cfiles=hello.cpp
set objfiles=hello.obj
set path=%clpath%
%clname% %includepath% /c %cfiles%
set path=%linkpath%
%linkname% %libpath% /subsystem:%subsystem% /entry:%entry% %libfiles% %objfiles%

这是输出：

Microsoft (R) C/C++ Optimizing Compiler Version 16.00.30319.01 for x64

hello.cpp
Microsoft (R) Incremental Linker Version 10.00.30319.01

hello.obj : error LNK2019: unresolved external symbol printf referenced in function main
hello.exe : fatal error LNK1120: 1 unresolved externals

只要我不尝试引用任何标准库函数，程序链接就可以了。我尝试弄乱 NODEFAULTLIB 和 DEFAULTLIB 开关，以及指定直接链接到的标准库，但无济于事。
