This is one of those problems that crop up from time to time.

What happened is that one of the sun-*.el files was byte-copmiled
without the proper macro definitions having been made first.  Though I
have 18.52, it appears that the macro in question is eval-in-window,
which is used in sun-fns.el and sun-mouse.el, and defined at thge top
of the latter.  The error you got is that the macro definition was
called as a function, which doesn't work.

The fix is to load the file defining the macro before byte-compiling
files that use the macro.  In your case, connect to the emacs/lisp
directory and do the sequence:

  (load-file "sun-mouse.el")
  (byte-compile-file "sun-mouse.el")
  (byte-compile-file "sun-fns.el")

or the equivalent interactive calls.  Check first that the defmacro in
question is in sun-mouse.el, as 18.45 may differ from 18.52.  To be
safe, you may want to load-file on all the sun-*.el files and
byte-compile them all.  Do all the load-files first.
