You mean https://lists.gnu.org/archive/html/bug-inetutils/2015-08/msg00005.html 
.

  Undeclared identifier MODE_TRAPSIG.
  Where does AIX define these macros?

It doesn't define this macro in any header file.

  Does <netdb.h> need its prerequisite headers included in a specified
  order?

No, as far as the gnulib documentation says.

  The mentioning of 'h_errno_which', unused and unknown to us,
  indicates that AIX is intentionally using non-portable constructs.

The macro h_errno expands to an expression that references a 'h_errno_which'
function. The error indicates that the inetutils source code probably uses
the macro in a declaration. It should use it only as an rvalue or lvalue.

  Are the declarations of these four identifiers conditionally available
  in <arpa/ftp.h>?

No AIX header files contains the identifiers typenames, formnames, strunames,
modenames. AIX <arpa/ftp.h> defines only macros without arguments, with
all-uppercase names.

Ignore it. AIX 1.3 and AIX 7.2 are two OS versions that are 24 years apart.
