--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
See e.g. ISO C99, 6.10.3/11, last sentence:
"If there are sequences of preprocessing tokens within the list of arguments
that would otherwise act as preprocessing directives, the behavior is
undefined."
Similarly for C++, see e.g. http://eel.is/c++draft/cpp.replace#11
So, the compiler can do anything with it.
