The minimum value of _POSIX_C_SOURCE for getnameinfo() was mistyped as 201112L
(not a real POSIX version), it should be 200112L. This is the same typo that
was fixed for getaddrinfo.3 in commit 94db8ae1824ada8561c3dbbbed88a8a9175c4886
According to the current documentation, this file should not compile, but
it does:
#define _POSIX_C_SOURCE 200112L
#include <netdb.h>
int (*mygetnameinfo)() = getnameinfo;
(If _POSIX_C_SOURCE is changed to 200111L, the program does no longer compile.)

Thanks for taking the time to report, but I think you must be looking
at a rather old version of the manual pages. It looks like that typo
was fixed about three years ago in the Git tree!
Thanks,
Michael

Oops, I accidently wrote getaddrinfo() in the subject. I meant to write
getnameinfo(), and I'm actually referencing the commit from three years
ago fixing it for getaddrinfo().

Ahh -- sorry, I should have looked more closely at your mail then.
Fixed now. Thanks for the report!

I just saw your commit, and it seems that you made another typo while fixing
the previous typo: It should be 200112L, not 20112L.
