/* This tests that multi-line macro callsites, which are defined
   in system headers and whose expansion contains a builtin followed
   by a non-builtin token, do not generate a line directive that
   mark the current file as being a system file, when performing
   non-integrated preprocessing. */
/* System files suppress div-by-zero warnings, so the presence of
   such indicates the lack of the bug.
