What operating system are you using? Some OSs (like Linux and FreeBSD) define
a type socklen_t while others do not (e.g. Darwin). Therefore, tdsystem.h
defines this type if HAVE_SOCKLEN_T is undefined.
#ifndef HAVE_SOCKLEN_T
typedef int socklen_t;
#define HAVE_SOCKLEN_T
#endif
HAVE_SOCKLEN_T is defined if the configure script's check for the type
socklen_t is successful. It seems that the file configure.in has to be
updated for your operating system.
