Prevent anonymous structure warning with Clang - "-fms-extensions" does not work

Question

I have an Xcode project that I am compiling with Clang using some third-party library with Visual Studio C code.

In a third-party library, anonymous structures are used in the header files (I cannot change this). So I get this warning:

"myfile.h: 47: 17: Anonymous structures are a GNU extension"

As described here, I tried passing "-fms-extensions" in the C flags of my Xcode project: http://clang.llvm.org/docs/UsersManual.html#microsoft-extensions

Bad luck. Any idea how to get rid of this warning?

int main(int argc, char **argv)

  Test test;
  test.a = 0;
