// This file is the input to a negative-compilation test for Google
// Test.  Code here is NOT supposed to compile.  Its purpose is to
// verify that certain incorrect usages of the Google Test API are
// indeed rejected by the compiler.
//
// We still need to write the negative-compilation test itself, which
// will be tightly coupled with the build environment.
//
// TODO(wan@google.com): finish the negative-compilation test.
