If I'm reading the referenced manpage correctly struct sockaddr is not
expected to have an ss_family member so the above define will not work
as is.
Instead I replaced the reference to ss_family with sa_family and now it
builds to completion.
I also ran the testsuite and it passes all tests.
The full log from running the testsuite is available at

I noticed that the compiler complained when building some of the test
x509self.c: In function 'server_start':
x509self.c:360: warning: passing argument 4 of 'setsockopt' from
incompatible pointer type
x509self.c: In function 'server':
x509self.c:434: warning: implicit declaration of function 'bzero'
x509self.c:434: warning: incompatible implicit declaration of built-in
function 'bzero'
