DECwindows conforms to X specs.....*not* 'BASED on X/Xt'.   MIT's  toolkit (Xt) is
only a reference implementation....most vendors  provide access to *some* features in
the MIT toolkit.  The protocol and Xlib are the most important specifications.   As far I 
know no vendor is under obligation to roll out revision levels at the same pace as MIT.
The vendors are paid by their customers to minimize bugs and provide stable software.
Also, most vendors ship other products, in addition to "toolkits".   Toolkits are the toys
of developers, not application end users.

So, who do you want to point fingers at?   XtR3  != DECwindows toolkit!
Mixing and matching different toolkits is nothing but a masochist adventure ;-)
The XtR3 stuff that you mention is supported under ULTRIX/DECwindows......and there
is a special library provided to link against.

A very daring and silly thing indeed to say in here!!
Get this straight........VMS IS NOT EQUAL TO DECwindows!
The DECwindows architecture supports MSDOS, U*IX, and VMS ( among others to come).
