add "review" lines in intl-encap-win32.c for all unseen functions in processed headers
-------------------- ChangeLog entries follow: --------------------
lib-src/ChangeLog addition:
2010-01-15 Ben Wing <ben@xemacs.org>
* make-mswin-unicode.pl:
Process the command `review'. Cause an error to happen if we try to
use the command, indicating that the command needs review to determine
how to handle it.
src/ChangeLog addition:
2010-01-15 Ben Wing <ben@xemacs.org>
* intl-encap-win32.c:
Add `review' lines for all functions seen in the headers that we
process but not yet associated with an encapsulation command.
These will cause an error to be signaled if these functions are
used.
* intl-auto-encap-win32.c:
* intl-auto-encap-win32.h:
Regenerate.

| 442 | 66 ;; #### We make list-mode-hook, as well as completion-setup-hook and |
| 67 ;; minibuffer-setup-hook, permanent-local so that it's possible to create | |
| 68 ;; buffers in these modes and then set up some buffer-specific | |
| 69 ;; customizations without resorting to awful kludges. (The problem here | |
| 70 ;; is that when you switch a buffer into a mode, reset-buffer is usually | |
| 71 ;; called, which destroys all buffer-local settings that you carefully | |
| 72 ;; tried to set up when you created the buffer. Therefore, the only way | |
| 73 ;; to set these variables is to use the setup hooks -- but if they are | |
| 74 ;; not declared permanent local, then any local hook functions that you | |
| 75 ;; put on them (which is exactly what you want to do) also get removed, | |
| 76 ;; so you would have to resort to putting a global hook function on the | |
| 77 ;; setup hook, and then making sure it gets removed later. I actually | |
| 78 ;; added some support for doing this with one-shot hooks, but this is | |
| 79 ;; clearly not the correct way to do things, and it fails in some cases, | |
| 80 ;; particularly when the buffer gets put into the mode more than once, | |
| 81 ;; which typically happens with completion buffers, for example.) In | |
| 82 ;; fact, all setup hooks should be made permanent local, but I didn't | |
| 83 ;; feel like making a global change like this quite yet. The proper way | |
| 84 ;; to do it would be to declare new def-style forms, such as defhook and | |
| 85 ;; define-local-setup-hook, which are used to initialize hooks in place | |
| 86 ;; of the current generic defvars. --ben | |
