Thanks for the report. But some more information might help:

What is the error when you don't have -lXau -lXdmcp specified? Do you
undertstand why xorg-7.3 needs these but not other X-implementations?

(extra credit:) how standard are libXau and libXdmcp? They seem to be present
on IRIX, Cygwin and Linuces, but I don't know about AIX or MacOS (for example).

These "standard X" libraries are ancient...why would xorg move things around
in a way almost guaranteed to break old programs?

I'm happy to make the above patch if it is safe for all machines. Otherwise,
we'll have to add code to the configure script to special-case this out.
