The missing macro is provided by glibc's cdefs.h. Thus, the wrong
cdefs.h was picked up.
The one from glibc is meant to be included when someone writes
#include <sys/cdefs.h>
The one from Gnulib is meant to be included when someone writes
#include <cdefs.h>
via
#include <libc-config.h>
If the wrong one was picked up, it sounds you have too many -I options
in your compilation commands.
Oops, the trace I posted wasn't complete. Here it is in it's full form.
The gnulib headers are included as expected.
Note, this is building with -mabi=ieeelongdouble option, thus this
requires both a sufficiently new gcc (8+) and glibc (2.23+).
