Re: fringe arrow conflict between compile and gud?

Using your reasoning for the compilation buffer, it would presumably be enough
to make overlay-arrow-position a local variable in Gnus.

Have you tried your patch? It look wrong to me. It shouldn't need a local
variable:

(defvar next-error-overlay-arrow-position nil)
(put 'next-error-overlay-arrow-position 'overlay-arrow-string "=>")
(add-to-list 'overlay-arrow-variable-list 'next-error-overlay-arrow-position)
etc

and replace (one) overlay-arrow-position
with next-error-overlay-arrow-position.
