That's an interesting twist. I wonder why MinGW does not have it
(or maybe my MinGW installation is too old).
And then we'll see whether it will blow up at run-time on XP or not -
having setsockopt() return an error is something our code will handle
("report, go on"), but on Windows, I wouldn't be surprised to see
"it fails with OS error" translate to "crash"...
