Widening the question: we're trying to get rid of a findutils construct:

-#if defined SIGCLD && !defined SIGCHLD
-# define SIGCHLD SIGCLD
-#endif

and need to know if gnulib's replacement <signal.h> needs to guarantee
this definition of SIGCHLD, or if the only platforms where only SIGCLD
existed are now so old to not be worth worrying about.
