They're not available at all on SGI IRIX either.  It is not the goal
of DJGPP to be 100% compatible with every Unix OS out there.  We must
consider all ramifications of each change.  In this case, we are
adding complexity to libc without a comparable increase in
portability.  In addition, the changes masquerade as POSIX standards,
which may confuse programmers and make their programs *less* portable,
without them being aware of it.  Overall, I'd say this change is not
suitable for djgpp.
