xemacs-faq.texi: Major rewrite.
Update all MS Windows info to current.
Redo section 6.1 almost completely.
Incorporate sections 1 and 2 of Hrvoje's FAQ.
etags.el: Fix infloop when going up to the root.
s\cygwin32.h: Don't unilaterally include ntplay, but only when we're compiling
with native sound (look in configure now).
event-msw.c: Fix yet more problems with C-g handling.
Implement debug-mswindows-events.
event-stream.c, events.h, signal.c, sysdep.h:
Rearrange the signal-handling code to eliminate the former
spaghetti logic paths in it. Document clearly what
"low-level" and "high-level" timeouts are. Rename some
functions with unclear names (e.g. "...alarm...") to names
that reflect what they actually do (e.g. "...async_timeout...").
Fix numerous bugs discovered in the process.
console-x.h, event-Xt.c, event-msw.c, frame-x.c:
Hopefully make XEmacs properly maintain the "iconified"
state on frames at all times. This should fix the "can't
delete a frame with C-x 5 0 when there's another iconified
frame out there" bug.
Put a notice in of further changes that should probably
be made to clean up the frame-visibility support.
(especially directed at Jan Vroonhof)
lisp.h, miscplay.c:
Rename SBufbyte to CBufbyte to avoid a misleading name.
Eliminate UChar, which is not used anywhere and contributes
no semantic info. Add a comment about the documentation-only
properties of the char/unsigned char typedefs. Add
SChar_Binary as an explicitly `signed' version of Char_Binary
and put back the `signed' declarations in miscplay.c.
alloc.c:
Use char typedefs.
console-msw.c, device-msw.c, dialog-msw.c, editfns.c, fileio.c, glyphs-eimage.c, menubar-msw.c, ntplay.c, objects-msw.c, realpath.c, redisplay-msw.c, select-msw.c, syswindows.h, win32.c:
Eliminate numerous C++ errors.
frame-msw.c:
Eliminate numerous C++ errors and Mule-ize.
glyphs-msw.c:
Eliminate numerous C++ errors and use char typedefs.
configure.in:
Fix problems detecting both native and Linux sound on Cygwin
when compiled with --with-msw=no.
Rearrange file-coding handling a bit to avoid warning when
compiling with Mule.
configure.in, configure.usage, INSTALL:
Document XEMACS_CC and corresponding compiler option --xemacs-compiler.
Explain how to build xemacs using a C++ compiler.

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.
