// 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 not added if there is already a definition of static_assert to
// ensure that we don't re-define the macro in the event the Microsoft assert.h
// header starts to define the macro some day (or the user defined their own
// macro with the same name). Test that the order of the macro definitions does
// not matter to the behavior.
