The relevant xlc warning is disabled by default. "xlc -qinfo=pro" does complain. <sys/types.h> provides no such prototype. <sys/socket.h> provides a getpeereid() prototype, but under C++ only. (For getpeername(), it provides both C and C++ prototypes.) Thus, the AIX documentation is wrong, and /usr/include is buggy. -- Sent via pgsql-committers mailing list (pgsql-committers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-committers
