Your RUN line will fail for non-mingw hosts.  Also, __declspec(selectany)
still needs to be tested for -fms-extensions.  Something like the following
would be more appropriate:

// RUN: %clang_cc1 -fms-extensions -fsyntax-only -verify -std=c++11 %s
// RUN: %clang_cc1 -triple i386-pc-mingw32 -fsyntax-only -verify -std=c++11
%s
