    I ran across this construct in ada-mode.el:

    (eval-when-compile
      (defconst ada-95-string-keywords
	'("abstract" "aliased" "protected" "requeue" "tagged" "until")
	"List of keywords new in Ada 95.
    Used to define `ada-*-keywords'."))

    Is there any point to the 'eval-when-compile'? Help for
    eval-when-compile says;

No, you may as well define that variable in all cases.
