Actually, the reason that happens is probably that src/template/hpux
forcibly adds -D_XOPEN_SOURCE_EXTENDED to CPPFLAGS. At least on my
old HPUX box, that's sufficient to select the more modern prototype
for accept and getsockopt; probably the same on yours.
So what I'm thinking is happening is that libpq expects size_t as
the argument type, but it's getting linked against a libc that
expects int as the argument type, and whatever HP is doing under
the hood fails to cope with that case. You might try removing
-D_XOPEN_SOURCE_EXTENDED from the template file --- I don't know if
that will have any bad side-effects, but it's worth a try to build
libpq that way.
