From 27a2ed83066c2de2ee8cd34add5b0cc8333e07c7 Mon Sep 17 00:00:00 2001
From: yamaoka <yamaoka>

Subject: [PATCH] (gnus-compile): Don't modify the value of
 `gnus-format-specs', generate compiled specs in
 `gnus-format-specs-compiled' instead; don't touch the
 dribble buffer. (gnus-update-format-specifications): Bind
 `gnus-format-specs' to `gnus-format-specs-compiled' if the
 latter is non-nil; use
 `gnus-update-format-specifications-1'.
 (gnus-update-format-specifications-1): Rename from
 `gnus-update-format-specifications'; update the value of
 `gnus-newsrc-file-version' if the updating is forced.
 (gnus-format-specs-compiled): New internal variable.
