// If the assert macro is defined in MS compatibility mode in C, we
// automatically inject a macro definition for static_assert. Test that the
// macro is properly added to the preprocessed output. This allows us to
// diagonse use of the static_assert keyword when <assert.h> has not been
// included while still being able to compile preprocessed code.
