dnl Renamed to AC_TYPE_SOCKLEN_T and some tweaks - David H - 2001-12-12

dnl
dnl Check whether sys/socket.h defines type socklen_t. Please note
dnl that some systems require sys/types.h to be included before
dnl sys/socket.h can be compiled.

dnl @synopsis ETR_SOCKET_NSL
dnl
dnl This macro figures out what libraries are required on this platform
dnl to link sockets programs. It's usually -lsocket and/or -lnsl or
dnl neither. We test for all three combinations.
