* make-docfile.c: Change whitespace and organization to reduce the
size of the diff against FSF Emacs sources and synch to Emacs 21.2.
Remove unused DO_REALLOC.
Mark XEmacs changes and additions more clearly.
Reintroduce previously deleted Emacs code inside #if 0 ... #endif.
* make-docfile.c (next_extra_elc): Replace goto with do-while.
* make-docfile.c (main): Put XEmacs-only args in one place.
* make-docfile.c (write_c_args): Change buff to buf to match
Emacs. Replace pointer arithmetic with simpler array syntax.
* make-docfile.c (scan_c_file): Note that DEFSIMPLE and DEFPRED no
longer exist. Correct the "name too long" test (off by one).
Die with message if a DEFUN has no docstring instead of hanging.
* make-docfile.c (scan_lisp_file): Introduce while loops used in
Emacs sources to skip consecutive blank lines.
2002-07-21 John Paul Wallington <jpw@xemacs.org>
* process.el (substitute-env-vars): New function; sync with
GNU Emacs 21.1.50.
(setenv): Add optional arg SUBSTITUTE-ENV-VARS; sync with
GNU Emacs 21.1.50.
2002-07-20 Mike Sperber <mike@xemacs.org>
* eval.c (run_post_gc_hook): Use more correct flags when running
post-gc-hook.
2002-07-20 Mike Sperber <mike@xemacs.org>
* process-unix.c (child_setup): Don't try to close file
descriptors for chid process once again---it's already being done
in close_process_descs.
(unix_create_process): Call begin_dont_check_for_quit to inhibit
unwanted interaction (and thus breaking of X event synchronicity)
in the child.
2002-07-15 Jerry James <james@xemacs.org>
* lisp.h: Make Qdll_error visible globally.
* symbols.c (check_sane_subr): Revert 2002-06-26 change.
Check only if !initialized.
* symbols.c (check_module_subr): Add parameter. Duplicate
check_sane_subr checks, but signal an error instead of asserting.
* symbols.c (defsubr): Use check_module_subr parameter.
* symbols.c (defsubr_macro): Ditto.

| 18 A dialog box description is a list. | |
| 19 | |
| 20 @itemize @bullet | |
| 21 @item | |
| 22 The first element of the list is a string to display in the dialog box. | |
| 23 @item | |
| 24 The rest of the elements are descriptions of the dialog box's buttons. | |
| 25 Each one is a vector of three elements: | |
| 26 @itemize @minus | |
| 27 @item | |
| 28 The first element is the text of the button. | |
| 29 @item | |
| 30 The second element is the @dfn{callback}. | |
| 31 @item | |
| 32 The third element is @code{t} or @code{nil}, whether this button is | |
| 33 selectable. | |
| 34 @end itemize | |
| 35 @end itemize | |
| 36 | |
| 37 If the callback of a button is a symbol, then it must name a command. | |
| 38 It will be invoked with @code{call-interactively}. If it is a list, | |
| 39 then it is evaluated with @code{eval}. | |
| 40 | |
| 41 One (and only one) of the buttons may be @code{nil}. This marker means | |
| 42 that all following buttons should be flushright instead of flushleft. | |
| 43 | |
| 44 The syntax, more precisely: | |
| 45 | |
| 46 @example | |
| 398 | 47 form := <something to pass to `eval'> |
| 48 command := <a symbol or string, to pass to `call-interactively'> | |
| 49 callback := command | form | |
| 50 active-p := <t, nil, or a form to evaluate to decide whether this | |
| 51 button should be selectable> | |
| 52 name := <string> | |
| 53 partition := 'nil' | |
| 54 button := '[' name callback active-p ']' | |
| 55 dialog := '(' name [ button ]+ [ partition [ button ]+ ] ')' | |

| 61 @defun popup-dialog-box dbox-desc | |
| 62 This function pops up a dialog box. @var{dbox-desc} describes how the | |
| 63 dialog box will appear (@pxref{Dialog Box Format}). | |
| 64 @end defun | |
| 65 | |
| 66 @xref{Yes-or-No Queries}, for functions to ask a yes/no question using | |
