I don't know why you're using libiberty but if it you are using the one
that comes from binutils then it still isn't a cygwin problem regardless
of the fact that you found a libiberty in cygwin's build area. Cygwin
has its own version of getopt and it is not the version that comes from
libiberty. There are no guarantees that cygwin's getopt header will
match whatever is in libiberty.a.
