I hope a better fix for that problem is this change:

-#if !FUNC_REALPATH_WORKS || defined _LIBC
+#if defined _LIBC || !FUNC_REALPATH_WORKS

which I just installed into Gnulib 
<https://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=18bc1ab1feca304d2a357407af8e29b3354496f2>. 
This sort of technique works in the "# if defined _LIBC || 
HAVE_FACCESSAT" line later on.
