[xemacs-hg @ 2003-03-09 02:27:27 by ben] To: xemacs-patches@xemacs.org i.c: Sleep between calls to check for I/O, since these calls are non-blocking. behavior.el: Allow other keywords for forward compatibility. cl-macs.el: Rewrite to eliminate byte-compiler warning when `return' is used without `finally'. cmdloop.el: Avoid truncated error messages for `end-of-file' and the like. cmdloop.el: Avoid char-int error after syncing. files.el: Eliminate byte-compile warnings. printer.el: Fix line-width calculations. #### This used to work. Someone's changes (perhaps by Michael Sperber?) seem to have messed something up. simple.el: Use new clear-left-side functions to avoid messages ending up on the same line as other output. xemacs.mak: Add override for info/ as well when separate source/build dirs. xemacs.mak: Order sections in main build process and add comments. Add additional dependencies to try and prevent later steps from happening when failures in earlier steps have occurred. Makefile.in.in: Order sections in main build process and add comments. Add additional dependencies to try and prevent later steps from happening when failures in earlier steps have occurred. alloc.c: Don't arbitrarily clear Vconfigure_info_directory since it messes up separate build/source dirs. console.c, console.h, device-msw.c, device.c: Add accidentally omitted msprinter console and data descriptions. print.c, console-msw.c: Add clear-left-side functionality to help keep stdio/stderr output from separate sources on separate lines. Generalize the different kinds of debugging output. Add dpa(). profile.c: Add better docs on Unix/Windows differences. regex.c: Fix problems with rel-alloc compilation caused by previous patch. emacs.c: Seg fault rather than abort on Cygwin, since gdb doesn't trap aborts properly. console-gtk-impl.h, console-gtk.h, console-msw.h, console-x-impl.h, console-x.h, dialog-gtk.c, dialog-x.c, event-msw.c, frame-gtk.c, frame-x.c, frameslots.h, glyphs-gtk.c, glyphs-x.c, gui-gtk.c, gui-x.c, inline.c, menubar-gtk.c, menubar-msw.c, menubar-x.c, scrollbar-gtk.c, scrollbar-x.c, ui-gtk.c: Delete popup-data object. Delete menubar_data field from frames, since its usage is frame-specific. Delete menubar-msw.h, gui-x.h, gui-gtk.h. Clean up handling of lwlib callback data GCPRO'ing and add missing GCPRO recomputation in widget code.

This directory contains C header files containing
operating-system-specific definitions.  Each file describes a
particular operating system.  The emacs configuration script edits
../config.h to include the appropriate one of these files, and then
each emacs source file includes config.h.

template.h is a generic template for system descriptions; it describes
the parameters a system file can specify.

General XEmacs Changes
---------------------------
The following is a list of those changes made globally across all
files.  They are not marked individually in each header file.  All
other changes should be preceded by a comment /* XEmacs change */.


1. Removed all #defines of [read|write|open|close].  This is now
   handled automatically by checking the INTERRUPTIBLE_IO etc. flags.

2. Removed all instances of #undef SIGIO and replaced them with
   #define BROKEN_SIGIO.  Jamie says:

   /* use BROKEN_SIGIO instead of this kludge -- jwz */

3. All instances of HAVE_GETWD, HAVE_DUP2, HAVE_UNISTD_H, NEED_UNISTD_H,
   HAVE_GETTIMEOFDAY and NEED_REALPATH removed.  We detect these
   automatically with configure.

4. All instances of HAVE_X11 replaced with HAVE_X_WINDOWS.  We don't
   support X10 or earlier so the HAVE_X11 define was purged.

5. Most of the signal crap (e.g. redefining sigsetmask, defining
   POSIX_SIGNALS) has been removed.  There are four possible
   signal paradigms that all systems fall into, and we auto-detect
   them in configure and handle them in syssignal.h.

6. Removed references to INTERRUPT_INPUT.  XEmacs does not use
   this bizarre way of reading input.

7. Removed references to BROKEN_FIONREAD.  FIONREAD is used only
   in INTERRUPT_INPUT and in the select() emulator, neither of
   which are supported in XEmacs.

8. Removed references to NOMULTIPLEJOBS.  This is unused in XEmacs
   and in FSF Emacs.

9. Removed references to HAVE_WAIT_HEADER and WAIT_USE_INT.
   They are unnecessary with the cleaned up syswait.h in XEmacs.
   (We autodetect sys/wait.h).  Instead, #define or #undef
   HAVE_UNION_WAIT.

10. Removed BSTRING.  Not used anywhere. (If the header file
    says there are bugs in bcopy() or the like, however, a
    #define BROKEN_BCOPY is added for reference.)

11. Removed #defines of bcopy, bzero, bcmp, index, rindex.
    XEmacs makes consistent use of the ANSI-equivalent
    functions memcpy, memset, memcmp, strchr, strrchr.

12. '#define subprocesses' removed.  Use '#define NO_SUBPROCESSES'
    if they don't exist.

13. References to HAVE_VFORK removed.  configure detects this.

14. Removed references to SYSV_SYSTEM_DIR, NONSYSTEM_DIR_LIBRARY,
    HAVE_SOCKETS, HAVE_SYSVIPC.  configure detects these.

15. Removed defines of HAVE_TERMIOS, HAVE_TERMIO, and
    HAVE_TCATTR (when HAVE_TERMIOS was also defined).
    configure detects these and systty.h automatically defines
    HAVE_TCATTR when HAVE_TERMIOS is defined.

16. Removed SETPGRP_RELEASES_CTTY.  Not necessary any more, with
    fixed definitions of EMACS_SEPARATE_PROCESS_GROUP et al.

17. Removed defines of NLIST_STRUCT.  configure detects this.

18. Removed defines of _setjmp and _longjmp.  configure detects this.

19. Removed all '#define static' business.  Defines NO_REMAP instead.

20. Removed defines of HAVE_MACH_MACH_H.  configure detects this.
