There is a special use of defvar designed specifically for that
situation:
(defvar <my-var-here>)
this will have no effect other than silence the byte-compiler.
Stefan
PS: If you really really want to, you can put it inside
`eval-when-compile', in which case it may currently work by accident,
but it logically shouldn't work (and may not work in the future) since
(defvar <foo>) does nothing when evaluated, and `eval-when-compile' asks
the byte-compiler to eval its argument instead of byte-compiling it.
