Re: gdb-ui.el assumes images support

    If you are talking about (eval-when-compile (require ...) ...) _in
    general_ then the following text from `(elisp)Coding Conventions'
    which encourages use of this construct to avoid compiler warnings
    should be changed:

	 Sometimes adding a `require' for another package is useful to
	 avoid compilation warnings for variables and functions defined in
	 that package.  If you do this, often it is better if the
	 `require' acts only at compile time.  Here's how to do that:

	      (eval-when-compile
		(require 'foo)
		(defvar bar-baz))

Thanks for finding this.  I think I will rewrite it not to suggest this.
