Problem:
--------
  This version of MXRN included on the freeware CD can't be built on OpenVMS 
  AXP but can be built on OpenVMS VAX (Motif V1.2)

1. If you look at the file clientlib.c, you can find the following useless 
line :

#if defined(UCX) || defined(WOLLONGONG)
#ifdef UCX
#include <sys/types.h> <---- Useless
#define CADDR_T
#define __CADDR_T
#define __SOCKET_TYPEDEFS

2. make_mwrn.com isn't Motif V1.2 compliant :

It can be compliant if you make the following modifications :

$ diff DKA0:[DISTRIB.MXRN-6-18-27]MAKE-MXRN.COM;14 ;-1

In fact, it's possible to create a make file able to build mxrn using 
either Motif V1.1 or Motif V1.2 in using something like :
@sys$update:decw$get_image_version sys$share:decw$xlibshr.exe ver
