+There is an inherent race between calling this function and performing

+Some platforms do not allow changing the access bits on symbolic
+links.  POSIX states that @code{fchmodat(@dots{},AT_SYMLINK_NOFOLLOW)}
+may fail with @code{EOPNOTSUPP} when called on a symlink, but some
+platforms, as well as the gnulib replacement, fail for any use of
+AT_SYMLINK_NOFOLLOW even if the target was not a symlink:
+glibc, Cygwin.
