Some Gnulib code (e.g., unlinkdir.c) relies on the Solaris-defined primitives in <priv.h> for that, e.g., priv_set_ismember (PRIV_SYS_LINKDIR) to test whether the current process can unlink directories (traditionally this required root privileges). Presumably this sort of thing could be extended and ported to POSIX 1.e, if someone wanted to do that.
