Subject: * gnus-clfns.el (subseq, merge, coerce, butlast): New compiler macros.
X-Git-Tag: t-gnus-6_15_0-09-quimby~2
X-Git-Url: http://git.chise.org/gitweb/?a=commitdiff_plain;h=b145c3b39301b1f134cb15148ba0b438f611d6f2;p=elisp%2Fgnus.git-

* gnus-clfns.el (subseq, merge, coerce, butlast): New compiler macros.
(mapc): Remove.

* nnwfm.el: Require `gnus-clfns' when compiling.
* nnshimbun.el: Ditto.
* nnfolder.el: Ditto.
* mm-util.el: Ditto.
* gnus-vers.el: Ditto.
* gnus-sum.el: Ditto.
* gnus-score.el: Ditto.
* gnus-nocem.el: Ditto.

* gnus-ofsetup.el: Don't require `gnus-clfns'.
(gnus-ofsetup-customize-done): Use `dolist' instead of `mapc'.
(gnus-setup-for-offline): Ditto.

* gnus-offline.el: Don't use `mapc' for binding some vars;
 don't require `gnus-clfns'.

* gnus-art.el: Use `dolist' instead of `mapcar' for defining
`gnus-article-read-summary-keys'.
