Perhaps I am half a step behind the rest of the world; I was unable to
get X11R2 clients built with SunOS 3.2 to work on anything but local (unix)
sockets. They would crash in bcopy() from XConnectDisplay() if environment
variable DISPLAY was set or "-display xxx:0" was used.

I tracked it down to what looks like abberhent behavior of gethostbyname()
on Sun's. They seem to return a unsigned long IP address where other machines
return a ptr to the same. (struct hostent *)->h_addr

(I first noticed this the other day doing a gethostbyname() on a pyramid -
it returned a ptr where the sun returned an IP address)

This diff to XConnDis.c fixes it on my suns.

< #ifdef SUN
< 			bcopy((char *)&host_ptr->h_addr, 
< 			      (char *)&inaddr.sin_addr, 
< 			      sizeof(inaddr.sin_addr));
< #else
193d187
< #endif

I assume everyone else in the world has figured this out by now. Perhaps
this will help some other lost sole who finally decides to upgrade from
X10R4 to X11R2 ;-)
