-1 can be *normal*, as MHD calls 'accept()' (possibly via multiple
threads when using a thread pool) until there are no more clients.  You
should check what errno says.

Also, in case accept4() is buggy on your platform, it is an
optimization; so you could #undef HAVE_ACCEPT4 if accept() +
setsockopt() works better. But I've not yet heard about a buggy
accept4() implementation...

Happy hacking!
