// Tests for Google Test itself. This verifies that Google Test can be
// linked into an executable successfully when built as a DLL on Windows.
// The test is not meant to check the success of test assertions employed in
// it. It only checks that constructs in them can be successfully linked.
//
// If you add new features to Google Test's documented interface, you need to
// add tests exercising them to this file.
//
// If you start having 'unresolved external symbol' linker errors in this file
// after the changes you have made, re-generate src/gtest.def by running
// scripts/generate_gtest_def.py.
