Hm, it got removed as part of
http://git.postgresql.org/gitweb/?p=postgresql.git;a=commit;h=9e3755ecb2d058f7d123dd35a2e1784006190962
but that's not an explanation, because
c.h includes sys/types.h. Which according to IBM's docs
https://www.ibm.com/support/knowledgecenter/en/ssw_aix_71/com.ibm.aix.basetrf1/getpeereid.htm
is the right thing to include. Given that xlc doesn't complain, I'll
just assume this is some issue with the headers gcc uses on aix, but I'm
far from confident.
Greetings,
