dnl Persuade AIX 5.2 <sys/socket.h> to declare CMSG_SPACE, CMSG_LEN.
|

dnl CMSG_FIRSTHDR is POSIX 2008, but CMSG_SPACE is only in RFC 3542.

[Define in order to get some macros on AIX systems.])

|
|
dnl Passfd prefers the POSIX use of msg.msg_control if the CMSG_* macros
|
|
dnl are present, but can fall back to BSD 4.3 style of msg.msg_accrights.
