It only sets it to size_t for System V release 4.2 and System V release 5
All others default to int like before.

I see below the output of config.guess on your machine is mips-sni-sysv4.
My patch would not reset to size_t  on your platform.

The native compilers on UnixWare complain if it's an int but it compiles.

Maybe what we need in is
 *sysv4*) AC_CHECK_LIB(resolv, strcasecmp);;
 *sysv4.2*) AC_DEFINE(SOCKARGLENTYPE,size_t);;
 *sysv5*) AC_DEFINE(SOCKARGLENTYPE,size_t);;
