Change NATNUMP to return 1 for positive bignums; changes uses of
it and of CHECK_NATNUM appropriately, usually by checking for an
integer in an appropriate range.
Add array-dimension-limit and use it in #'make-vector,
#'make-string. Add array-total-size-limit, array-rank-limit while
we're at it, for the sake of any Common Lisp-oriented code that
uses these limits.
Rename check_int_range to check_integer_range, have it take
Lisp_Objects (and thus bignums) instead.
Remove bignum_butlast(), just set int_n to an appropriately large
integer if N is a bignum.
Accept bignums in check_sequence_range(), change the functions
that use check_sequence_range() appropriately.
Move the definition of NATNUMP() to number.h; document why it's a
reasonable name, contradicting an old comment.

* automated/lisp-tests.el:
* automated/lisp-tests.el (featurep):
* automated/lisp-tests.el (wrong-type-argument):
* automated/mule-tests.el (featurep):
Check for args-out-of-range errors instead of wrong-type-argument
errors in various places when code is handed a large bignum
instead of a fixnum.
Also check for the wrong-type-argument errors when giving the same
code a non-integer value.

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_ascstring', |
428 | 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. |
