This seems to work fine for socat, but for socat-debuginfo 2.0.0-b6, the
build fails because IPV6_DSTOPTS is undefined.  Cygwin doesn't seem to
define IPV6_DSTOPTS.  In Ubuntu, it's defined in
/usr/include/linux/in6.h (value 59), along with a whole bunch of other
IPv6 socket options.

I'm not sure what the best solution is here.  I could define it locally,
but would it be better for Cygwin to bring in the missing definitions?
