------ signal-code changes ------
data.c, device-tty.c, emacs.c, floatfns.c, linuxplay.c, nas.c,
process-unix.c, signal.c, sunplay.c, sysdep.c, syssignal.h:
use EMACS_SIGNAL everywhere instead of playing preprocessing
games with signal().
s\windowsnt.h, s\mingw32.h, syssignal.h:
Remove mswindows signal code from s+m headers and move to
syssignal.h as one of the five ways of signal handling,
instead of playing preprocessing games.
fileio.c, sysdep.c:
Rename sys_do_signal to qxe_reliable_signal.
signal.c, process-unix.c, profile.c:
Create set_timeout_signal(); use instead of just EMACS_SIGNAL
to establish a signal handler on a timeout signal; this does
special things under Cygwin.
nt.c:
Eliminate term_ntproc(), which is blank; used as a SIGABRT
handler, which was wrong anyway.
nt.c, win32.c:
Move signal code from nt.c to win32.c, since Cygwin needs it
too when dealing with timeout signals.
s\cygwin32.h:
Define CYGWIN_BROKEN_SIGNALS.
------ other changes ------
s\mingw32.h:
Fix problems with NOT_C_CODE being in the wrong place and
excluding defines needed when building Makefile.in.in.

s\usg5-4.h, s\windowsnt.h, s\xenix.h:
Rename 'GNU Emacs' to XEmacs in the copyright and comments.
nas.c:
Stylistic cleanup. Avoid preprocessing games with names such
as play_sound_file.

|---|---|
| 428 | 1 This directory contains the source files for the C component of XEmacs. |
| 2 Nothing in this directory is needed for using XEmacs once it is built | |
| 3 and installed, if the dumped Emacs is copied elsewhere. | |
| 4 | |
| 5 See the files ../README and then ../INSTALL for installation instructions. | |
| 6 | |
| 7 Under Unix, the file `Makefile.in.in' is used as a template by the script | |
| 8 `../configure' to produce `Makefile.in'. The same script then uses `cpp' | |
| 9 to produce the machine-dependent `Makefile' from `Makefile.in'; | |
| 10 `Makefile' is the file which actually controls the compilation of | |
| 11 Emacs. Most of this should work transparently to the user; you should | |
| 12 only need to run `../configure', and then type `make'. | |
| 13 | |
| 14 General changes for XEmacs: | |
| 15 --------------------------- | |
| 16 1. Lisp objects. | |
| 17 | |
| 18 -- XFASTINT has been eliminated. Use of this expression as an lvalue | |
| 19 is incompatible with the union form of Lisp objects, and use as | |
| 20 an rvalue is likely to lead to errors and doesn't really save much | |
| 21 time. Expressions of the form `XFASTINT (obj) = num;' get replaced | |
| 22 by `obj = make_int (num);' or `XSETINT (obj, num);' and | |
| 23 expressions of the form `num = XFASTINT (obj);' get replaced by | |
| 24 `num = XINT (obj);'. Use Qzero in place of `make_int (0)'. | |
| 25 | |
| 26 -- Use of XTYPE gets replaced by the appropriate predicate. Using | |
| 27 XTYPE only works for the small number of types that are not stored | |
| 28 using the Lisp_Record type (int, cons, string, and vector). For | |
| 29 example, `(XTYPE (foo) == Lisp_Buffer)' gets replaced by | |
| 30 `(BUFFERP (foo))'. | |
| 31 | |
| 32 -- `XSET (obj, Lisp_Int, num)' gets replaced by `XSETINT (obj, num)', | |
| 33 for consistency. | |
| 34 | |
| 35 -- Some occurrences of XSET need to get replaced by XSETR -- | |
| 36 specifically, those where the type is not a primitive type | |
| 37 (primitive types are int, cons, string, and vector). | |
| 38 | |
| 39 -- References to `XSTRING (obj)->size' get replaced with | |
| 40 `XSTRING_LENGTH (obj)'. This is currently for cosmetic reasons | |
| 41 but there may be other reasons in the future. (This change is | |
| 42 currently incomplete in the source files.) | |
| 43 | |
| 44 | |
| 45 2. Storage classes: | |
| 46 | |
| 47 -- All occurrences of `register' should be replaced by `REGISTER'. | |
| 48 It interferes with backtraces so we disable it if DEBUG_XEMACS | |
| 49 is defined. | |
| 50 | |
| 51 | |
| 52 3. Errors, messages, I18N3 snarfing: | |
| 53 | |
| 54 -- Errors are continuable in XEmacs but are not in FSF Emacs. | |
| 55 Therefore, it's important that functions do something reasonable | |
| 56 if an error gets continued. If you want to signal a non- | |
| 57 continuable error, the call to Fsignal() gets put inside a | |
| 58 `while (1)' loop. To facilitate this, and also for proper I18N3 | |
| 59 message snarfing, most calls to Fsignal() have been replaced by | |
| 60 calls to signal_error(), signal_simple_error(), etc. Look at | |
| 61 eval.c for a classification of various error functions. | |
| 62 | |
| 63 -- Constant strings occurring in source files need to get wrapped | |
| 64 in a call to GETTEXT (or if inside of a call to `build_string', | |
| 65 change that function to `build_translated_string') if they don't | |
| 66 occur in certain places where the I18N3 message snarfer will see | |
| 67 them. For a complete discussion of this, see the file | |
| 68 lib-src/make-msgfile.lex. | |
| 69 | |
| 70 NOTE: I18N3 support is not currently working, so the above may | |
| 71 or may not apply. Thus it is not a good idea to add random | |
| 72 GETTEXTs, unless you really know what you are doing. | |
| 73 | |
| 74 -- Calls to `fprintf (stderr, ...)' and `printf (...)' get replaced | |
| 75 with calls to `stderr_out' and `stdout_out'. This is for I18N3 | |
| 76 message snarfing. | |
| 77 | |
| 78 4. Initialization: | |
| 79 | |
| 80 -- FSF constructs like `obj = intern ("string"); staticpro (&obj);' | |
| 81 get replaced by `defsymbol (&obj);'. This is for code cleanness | |
| 82 and better purespace usage. | |
| 83 -- FSF constructs like | |
| 84 obj = intern ("error"); | |
| 85 Fput (obj, Qerror_message, "message"); | |
| 86 Fput (obj, Qerror_conditions, some list); | |
| 87 get replaced by calls to deferror(). See the definition of | |
| 88 deferror() for how the correct arguments to pass. This is for | |
| 89 code cleanness and I18N3 message snarfing. | |
| 90 -- Code in keys_of_foo() functions has been moved into Lisp. |
