  [[I tried replying to Bill directly but neither his path nor reply-to
address worked.]]

  I was one of the people who flamed and still have yet to receive a
rational answer why we can't back support the old XGetDefault behavior.
We now have a backward compatibility routine which isn't backwards
compatible.  Oh well.

  Here's a patch to XGetDefault that will make it work the way it used to.
Note, as Bob points out, you should change your code to use the Xrm stuff
directly for compatibility reasons.

P.S.  The following patch is relative to MIT patch level 14.

-----
%%% mit/lib/X/XGetDflt.c:
%%% 
%%% Fix XGetDefault so that XGetDefault(dpy, program, name) works when name
%%% containing a compound string (``foo.bar'', etc.)
