I've downloaded and built clang version 3.0 in order to play around a bit with C++11 features, however I get this error (even though I am using the -Wc++11-extensions flag).
我已经下载并构建了clang版本3.0，以便在c++11的特性上运行，但是我得到了这个错误(尽管我使用的是-Wc++11-extensions标志)。
S:\llvm\code>clang++.exe -Wc++11-extensions variadic.cpp

I've built clang with VS10 on Windows 7 (64bit) and the build passed successfully.
我在Windows 7(64位)上使用VS10构建了clang，并且成功地通过了构建。
Edit: As @cli_hlt pointed out this is a warning not an error, the error is something I did not paste unable to execute command: program not executable. The root cause for that was that link.exe was not in the PATH. Once I ran from a VS command prompt all was well.
编辑:@cli_hlt指出这是一个警告，不是错误，错误是我没有粘贴不能执行命令的东西:程序不可执行。造成这一现象的根本原因是链接。exe不在路上。当我从VS命令提示符运行时，一切都很好。

You are getting a warning, not an error.
你得到的是警告，而不是错误。
The -W switch is used to enable compiler warnings. So for my understanding, by using -Wc++11-extensions you tell the compiler to warn you if you are using C++11 extensions.
-W开关用于启用编译器警告。因此，根据我的理解，通过使用-Wc++11扩展，您可以告诉编译器，如果您使用c++11扩展，就可以警告您。
And thats exactly what happens here.
这就是这里的情况。
