I don't quite understand this.  socat-debuginfo is just a by-product of
building socat.  How can building socat work but building debuginfo fail?!?

I don't think so.  I checked the available options on Windows again,
and IPV6_DSTOPTS is not supported.  I applied a small patch a few
minutes ago to add a few socket options our headers were missing,
but there are still a lot of Linux socket options not supported on
Windows which hinders CYgwin to support them.

Any chance you could tweak this piece of code to be built only
if IPV6_DSTOPTS is defined?
