Temporary header file '/tmp/EtHcP2yos0/dump1.h' with the following content will be compiled to create GCC translation unit dump:

  // add defines
  #define __STDC_VERSION__ 201710L
#define _GXX_NULLPTR_T
#define CLUTTER_ENABLE_COMPOSITOR_API 1
#define _REGEX_NELTS(n)
#define _Atomic
#define PACKED

  // add includes
  #include "/usr/include/lua5.1/lua-rrd.h"
  #include "/usr/include/lua5.2/lua-rrd.h"
  #include "/usr/include/lua5.3/lua-rrd.h"

The GCC parameters:
