There seems to be a bug in XtGetApplicationResources that appears
on Sun4's (4.0) but not on Vaxstations (Ultrix 3.0) or DECstation 3100
(Worksystem V2.0, which I believe is Ultrix 3.0).  All are using R4 from
MIT (installed by me).

Compile with -lXt -lX11

The bug is that some resources are parsed correctly and one in particular
is not.  Here is a whole program which demonstrates the point.

Run with -portrait or -P and the landscape variable should be set to 0.
This one doesn't work on a sun4.
Run with -right and justify should be set to 1.  It sets justify to 16777216
instead, which is 1000000 hex (byte order problem?)

I am mailing to xbugs, but if anyone has any ideas, I would appreciate it.
