-dnl @synopsis AC_FUNC_ACCEPT_ARGTYPES
-dnl
-dnl Checks the data types of the three arguments to accept(). Results are
-dnl placed into the symbols ACCEPT_TYPE_RETURN and ACCEPT_TYPE_ARG[123],
-dnl consistent with the following example:
-dnl
-dnl #define ACCEPT_TYPE_RETURN int
-dnl #define ACCEPT_TYPE_ARG1 int
-dnl #define ACCEPT_TYPE_ARG2 struct sockaddr *
-dnl #define ACCEPT_TYPE_ARG3 socklen_t
-dnl
-dnl NOTE: This is just a modified version of the AC_FUNC_SELECT_ARGTYPES
-dnl macro. Credit for that one goes to David MacKenzie et. al.

-# PostgreSQL local changes: In the original version ACCEPT_TYPE_ARG3
-# is a pointer type. That's kind of useless because then you can't
-# use the macro to define a corresponding variable. We also make the
-# reasonable(?) assumption that you can use arg3 for getsocktype etc.
-# as well (i.e., anywhere POSIX.2 has socklen_t).
-#
-# arg2 can also be `const' (e.g., RH 4.2). Change the order of tests
-# for arg3 so that `int' is first, in case there is no prototype at all.
-#
-# Solaris 7 and 8 have arg3 as 'void *' (disguised as 'Psocklen_t'
-# which is *not* 'socklen_t *'). If we detect that, then we assume
-# 'int' as the result, because that ought to work best.
-#
-# On Win32, accept() returns 'unsigned int PASCAL'
-# Win64 uses SOCKET for return and arg1
