Yes, the same thing that gnulib does in getdelim:

#if !HAVE_FLOCKFILE
# undef flockfile
# define flockfile(x) ((void) 0)
#endif
#if !HAVE_FUNLOCKFILE
# undef funlockfile
# define funlockfile(x) ((void) 0)
#endif

We can just duplicate the code for now and put it in the todo list.

Same idea I had.

Yeah, I can help testing it on MacOS.  Thank you very much.
