JB		 1Wed Apr 5 14:32:51 1995 Gary Houston <ghouston@actrix.gen.nz>
2
3 * unix.c, ioext.c, posix.c, sys.c: Scheme name changes,
4 semantic cleanups, the port table, missing system calls
5 and coding cleanups from ghouston@actrix.gen.nz
6
7Thu Mar 16 14:37:38 1995 Tom Lord <lord@x1.cygnus.com>
8
9 * guile.c: fixed the gcc-specific definition of the macro "AT(x)".
10
11 * guile.c (gscm_init_from_fn): Parameterize what init functions
12 get called (see guile_ks, below).
13
14 * guile-mini.c (guile_mini): a minimalist alternative to guile_ks.
15
16 * guile-ks.c (guile_ks): factor out the call to optional inits to
17 a separate file so you can link against libguile without getting
18 the kitchen sink.
19
20 * Ginit.scm (try-load of "ScmInit.scm"): Be robust in the absense
21 of a binding for the environment varialbe HOME. Try
22 (getpw (geteuid)) or just use "/".
23
24
25Thu Mar 9 15:35:20 1995 Tom Lord <lord@x1.cygnus.com>
26
27 * gmain.c (main): Print additional error message if init file
28 can't be opened.
29
30 * guile.c (initialize_gscm): Report an error if the
31 init file can't be opened.
32
33Thu Mar 23 23:22:59 1995 Aubrey Jaffer (jaffer@jacal)
34
35 * scm.texi (I/O-Extensions): Finished.
36
37 * Init.scm (scm:load): `loading' messages now indented.
38
39Sat Mar 4 20:58:51 1995 Aubrey Jaffer (jaffer@jacal)
40
41 * scm.texi: documentation finished for "posix.c" and "unix.c".
42
43 * posix.c (scm_getgroups): added.
44
45 * posix.c (makfrom0str): According to glibc.info, some field in
46 structures like pwent may have NULL pointers. Changed makfrom0str
47 to return BOOL_F in this case.
48
49Thu Mar 2 12:52:25 1995 Aubrey Jaffer (jaffer@jacal)
50
51 * time.c: CLKTCK set from CLOCKS_PER_SEC, if available. Metaware
52 HighC ported.
53
54 * scm.h: USE_ANSI_PROTOTYPES now controls prototypes (was
55 __STDC__). This allows an overly fussy compiler to still have
56 __STDC__.
57
58 From: dorai@ses.com (Dorai Sitaram)
59 * ioext.c (l_utime): include files fixed for __EMX__
60
61Sun Feb 26 23:46:18 1995 Tom Lord <lord@x1.cygnus.com>
62
63 * repl.c (scm_app_wdr): Like scm_apply, but takes an error function.
64 The caller's continuation is never captured or escaped.
65 The error function is invoked as with scm_cwdr.
66
67Sun Feb 26 21:03:04 1995 Aubrey Jaffer (jaffer@jacal)
68
69 * sys.c (gc_mark gc_sweep): tc7_ssymbol now gets GCed because it
70 gets used for non-GCed strings in scm_evalstr scm_loadstr.
71 (mkstrport cwos cwis): changed so caller's name is passed into
72 mkstrport().
73
74 * repl.c
75 (scm_eval_string scm_evalstr scm_load_string scm_loadstr): added
76 for easier C to scheme callbacks.
77 (loadport): variable added so lreadr() and flush_ws()
78 increment linum only when reading from the correct port.
79 (def_err_response): now handles ARGn for argument numbers > 5 and
80 unknown position arguments.
81
82 * dynl.c: Dynamic Linking now sets and restores *load-pathname*
83 around the init_ call.
84
85Sat Feb 25 11:03:56 1995 Aubrey Jaffer (jaffer@jacal)
86
87 * scm.c (lsystem getenv softtype ed vms_debug): moved from scl.c.
88 (add_feature): moved from repl.c.
89 (features): init table removed (caused multiple symbols).
90
91Fri Feb 24 23:48:03 1995 Aubrey Jaffer (jaffer@jacal)
92
93 * scm.c (scm_init_extensions COMPILED_INITS): Added so that
94 statically linked, compiled code can be initialized *after* most
95 of Init.scm has loaded.
96
97Wed Feb 22 15:54:01 1995 Aubrey Jaffer (jaffer@jacal)
98
99 * subr.c (append): Added check for bad arguments and fixed errobj.
100
101Sun Feb 19 01:31:59 1995 Aubrey Jaffer (jaffer@jacal)
102
103 * ioext.c (exec execp): changed so that 2nd arguments is argv[0]
104 (like posix) and renamed to execl and execlp.
105 (execv execvp): added.
106
107Sat Feb 11 17:30:14 1995 Aubrey Jaffer (jaffer@jacal)
108
109 * ioext.c (lexec): moved from repl.c and scm.c.
110 (lexecp i_exec l_putenv): added.
111
112 * posix.c (open_pipe l_open_input_pipe l_open_output_pipe
113 prinpipe): moved from ioext.c.
114 (l_fork): added.
115
116Fri Feb 10 10:50:03 1995 Aubrey Jaffer (jaffer@jacal)
117
118 * scl.c (num2long long2num): moved here from subr.c.
119 (num2ulong): fixed (< to >=) bug.
120
121 * unif.c (aset array2list array_ref cvref): uniform integers and
122 unsigned integer arrays now handle full size integers (and
123 inexacts) using num2long, num2ulong, long2num, and ulong2num when
124 INUMS_ONLY is not defined.
125
126 * scmfig.h (INUMS_ONLY): defined when INUMs are the only numbers.
127
128Wed Feb 8 17:57:26 1995 Tom Lord (lord@x1.cygnus.com)
129
130 * Ginit.scm (stand-alone-repl): Use new function (rooted-repl)
131 (rooted-repl): new function
132
133Tue Jan 31 16:46:26 1995 Tom Lord (lord@x1.cygnus.com)
134
135 * repl.c (lreadr): compare string constant names
136 in a case insensative way.
137
138 (scm_lread): Take an optional parameter CASEP.
139 If specified and not #f, then symbols are read
140 in a case sensative way.
141
142 If not specified, the state variable default_case_i is checked
143 (a C int, either 0 or 1). The state variable hasn't been
144 exposed and so is constant and depends on compile-time flags --
145 but in the future it might be made more explicit if there is a
146 need.
147
148Sun Jan 29 23:22:40 1995 Aubrey Jaffer (jaffer@jacal)
149
150 * scm.texi (Overview): scm.1 converted to texinfo format and
151 incorporated.
152
153Sat Jan 28 23:11:40 1995 Tom Lord (lord@x1.cygnus.com)
154
155 * repl.c (compiled-library-path): return the value of the
156 compile-time cpp macro "LIBRARY_PATH" or #f.
157
158 * Ginit.scm: use the above path to find slib on unix.
159 This solution should be generalized.
160
161Fri Jan 27 19:58:27 1995 Tom Lord (lord@x1.cygnus.com)
162
163 * sys.c (gc_sweep): Fixed a gc bug that caused circular free-lists
164 resulting in Cells that thought they were free long after they
165 were allocated for some nefarious purpose or other.
166
167 * Makefile.in (manifest): ship all pieces of the info manual.
168 Typos fixes from ghouston.
169
170Thu Jan 26 01:52:00 1995 Tom Lord <lord@x1.cygnus.com>
171
172 From: cessu@cs.hut.fi (Kenneth Oksanen)
173
174 * configure.in:
175 AC_CHECK_LIB(nsl, gethostent)
176 AC_CHECK_LIB(ucb, bzero)
177 AC_CHECK_LIB(socket, socket)
178 AC_CHECK_LIB(bsd, bzero)
179
180
181 From: brent@jade.ssd.csd.harris.com (Brent Benson)
182
183 * gmain.c: line 31: In ANSI C, string literals cannot span multiple
184 source lines.
185
186 * guile.c: line 592: The two cases in the ifdef are reversed, AT(X)
187 should expand to nothing if you are *not* using GNUC.
188
189 * ioext.c: line 29: On my system it is necessary to
190 include <unistd.h> *before* <sys/stat.h> in order to
191 have the correct types defined.
192
193 * ioext.c: line 194: Declaration of popen conflicts with my system's
194 popen() defined in <unistd.h>. Let the header file provide the
195 prototype!!
196
197Sun Jan 22 11:13:58 1995 Aubrey Jaffer (jaffer@jacal)
198
199 * scm.texi (Internals): code.doc converted to texinfo format.
200 Much added and reorganized. code.doc removed.
201
202Thu Jan 19 00:40:11 1995 Aubrey Jaffer (jaffer@jacal)
203
204 * subr.c (logbitp logtest): added.
205
206Mon Jan 16 01:42:20 1995 Tom Lord <lord@x1.cygnus.com>
207
208 * repl.c (scm_repl): takes two arguments now (prompt and top-level).
209 Callable from Scheme.
210
211 * sys.c (scm_init_storage): only use stdin if scm_take_stdin is true.
212 Otherwise, use an empty string port. If using stdin, make it
213 unbuffered.
214
215Sun Jan 15 21:51:37 1995 Tom Lord <lord@x1.cygnus.com>
216
217 * sys.c (scm_mkarray, scm_free_array, mark_arrays): support for
218 C programs. malloc/free style interface to allcoating
219 protected storage of type SCM*.
220
221Sun Jan 15 17:49:43 1995 Tom Lord (lord@x1.cygnus.com)
222
223 * guile.c: new file. Friendly C interface for Guile.
224 (see file GUILE)
225
226 * repl.c (scm_cwdr): added call-with-dynamic-root (see scm.texi).
227
228Sat Jan 14 23:35:21 1995 Tom Lord (lord@x1.cygnus.com)
229
230 * repl.c, subr.c: re-arrangement, commenting
231 of source in preparation for pulling repls apart
232 for libguile.
233
234Wed Jan 11 14:45:17 1995 Aubrey Jaffer (jaffer@jacal)
235
236 * scl.c (num2ulong): checks for bignum sign and magnitude added.
237
238 * subr.c (logand logior logxor lognot): lognot restriction to
239 INUMs removed. Logand, logior, and logxor now will work for up to
240 32 bit signed numbers.
241
242Tue Jan 10 13:19:52 1995 Aubrey Jaffer (jaffer@jacal)
243
244 * repl.c (def_err_response): Circuitous call to quit() replaced
245 with exit(EXIT_FAILURE);
246 (everr): Now calls def_err_response() in interrupt frame if
247 errjmp_bad or there are dynwinds to do. This prevents silent
248 failure in batch mode.
249
250
251Mon Jan 9 00:12:14 1995 Aubrey Jaffer (jaffer@jacal)
252
253 * repl.c (handle_it): Now discards possibly used top freelist cell
254 for GC safety. Also now just punts if errjmp_bad.
255
256 * scm.texi: converted from MANUAL. GUILE documentation merged in.
257
258Sat Jan 7 13:51:04 1995 Miles Bader (miles@eskimo.com)
259
260 * mrequire.scm: New file: Wrapper for slib require/provide that
261 makes it modular (that is, each slib package is loaded into its
262 own module, and sees only other modules that it requires).
263
264 * defmod.scm: Allow use-interface in the default module.
265
266 * libguile.scm: Put symbols common to both guile and scm
267 interfaces into the internal interface `EXTRA' (which is included
268 by both). Other random shuffling, mostly to make slib happy.
269
270 * modops.scm (extend-interface, export-interface, export): Add
271 another operation type, #f, which turns off automatic exporting of
272 the current source interface when finishing up with it. This is
273 used by export-interface to prevent trying to export all symbols.
274
275 * modops.scm (import): No longer signal an error when trying to
276 export a whole module, as we want to do this sometimes.
277
278 * Ginit.scm: No longer try to load require.scm, or depend on it;
279 In the case of getopt, we just load it manually. Also make
280 defmacro module-safe.
281
282Sat Jan 7 01:54:11 1995 Tom Lord <lord@x1.cygnus.com>
283
284 * sys.c (scm_intern_obarray_soft): Reserve room for symbol slots.
285
286 * sys.c (scm_makstr, scm_makfromstr): added an extra parameter SLOTS.
287 The parameter means:
288 0: same as the old behavior
289 1: not useful
290 > 1: allocate SLOTS - 1 extra slots in the string storage.
291
292 The base address of SLOTS, an array of SCM, is at SLOTS(obj).
293 This is for symbol slots, and later for procedure slots.
294 If you use this in the constructor for your new type (usually
295 done by creating a string and then invoking SETLENGTH to change
296 its type), you are responsible for making sure slot contents
297 are properly gc'ed.
298
299 Callers of these were fixed as well.
300
301Tue Jan 3 14:30:34 1995 Miles Bader (miles@eskimo.com)
302
303 * modops.scm, extlibs.scm, libguile.scm, defmod.scm: New files:
304 These implement the user-level module system.
305
306 * sys.c (scm_sym2vcell): Add another argument: definedp, which is
307 passed as additional argument to the lookup-thunk (if any).
308 If this argument is BOOL_T, this lookup is for a define (which
309 has somewhat different semantics for modules); otherwise it
310 should be satisfied with an existing variable. If the thunk
311 returns BOOL_F (meaning there was no such variable), sym2vcell
312 returns BOOL_F as well.
313 * eval.c (scm_lookupcar, scm_m_define): Use the new sym2vcell param.
314 * variable.c (scm_builtin_var): Use the new sym2vcell param.
315
316 * eval.c (scm_top_level_env): New function: return an environment
317 using the given top-level-lookup thunk.
318 * eval.c (scm_eval2): Use scm_top_level_env.
319 * eval.c (scm_eval): Use an env with a top-level lookup thunk from
320 scm_top_level_lookup_thunk_var (aka *top-level-lookup-thunk*).
321 * eval.c (scm_neval): New function: just like scm_eval, but may
322 destroy its argument. Known in scheme as eval!.
323
324 * repl.c (scm_repl, scm_tryload, lreadr): Use scm_neval, not eval_3.
325
326 * Ginit.scm (make-module): Use the new definition of top-level thunks.
327 * Ginit.scm (set-current-module): Set *top-level-lookup-thunk* too.
328 * Ginit.scm: Trash all the repl stuff; we just use the C repl now.
329 Load the user module system.
330
331 * Makefile.in: Install the user-module implementation files.
332
333Mon Jan 2 16:27:25 1995 Miles Bader (miles@eskimo.com)
334
335 * Ginit.scm (repl:repl): Have the guile repl redefine try-load
336 instead of load, as this is the SCM primitive.
337 (module-for-each): Write module-for-each.
338 (module-search): Make this recurse into each module use-list
339 entry, as per the low-level module spec.
340 (define-macro): Make this function usable by modules that don't
341 have access to the internals of the guile module.
342
343Sun Jan 1 22:30:25 1995 Tom Lord <lord@x1.cygnus.com>
344
345 * repl.c (scm_iprin1), subr.c (scm_lock_vector, scm_unlock_vector,
346 scm_lvector_ref, scm_lvector_set):
347
348 Added locked vectors. See N
349
350Sat Dec 31 15:45:22 1994 Miles Bader <miles@eskimo.com>
351
352 * Ginit.scm:
353 Add define-macro, delq!.
354
355 Add a module print-function, and some new name fields
356 to the module that the modops code uses to make modules
357 print nicely (e.g., #<interface guile/module 7a89c>)
358
359
360 * eval.c(ceval): Here's a patch that makes closures & subrs
361 self-evaluating.
362
363
364Wed Dec 28 00:31:22 1994 Tom Lord <lord@cygnus.com>
365
366 * scm.c (raise): use kill not raise, since it is more portable.
367
368Wed Dec 21 05:18:47 1994 Tom Lord <lord@x1.cygnus.com>
369
370 * eval.c (scm_eval2): Two argument eval. The
371 second argument is #f or a proc returning a variable.
372
373Fri Dec 9 00:40:26 1994 Tom Lord <lord@x1.cygnus.com>
374
375 * eval.c (scm_fasl_eval): eval without copying the source form.
376 This is just a temporary hack.
377
378Sun Dec 4 21:50:37 1994 Tom Lord <lord@x1.cygnus.com>
379
380 * eval.c (scm_ceval): Added special forms LITERAL-VARIABLE-SET!
381 and LITERAL-VARIABLE-REF. The first argument of each is a
382 variable object (see variable.c). The second argument
383 of set! is an expression. They do what you'd expect.
384 -SET! returns UNSPECIFIED.
385
386 Note that one can not read a form which uses literal-variable*
387 correctly because there is no way to read a variable object.
388 These forms exist for the sake of the module system.
389
390Fri Dec 2 19:52:40 1994 Tom Lord (lord@x1.cygnus.com)
391
392 * subr.c (string->obarray-symbol, intern-symbol, unintern-symbol,
393 symbol-set!, symbol-binding)
394 Multiple obarrays.
395
396 * variable.c (scm_make_variable, scm_variable_{ref,set}
397 Implemented variables. Variables are anonymous
398 objects holding one settable value.
399
400Wed Nov 30 04:31:18 1994 Tom Lord (lord@x1.cygnus.com)
401
402 * *.[ch]: renamed all global identifiers to have the prefix scm_.
403
404 * sys.c (gc_sweep, scm_mark_locations, scm_init_heap):
405
406 Modified gc to allow objects of any multiple of sizeof(CELLPTR).
407 In addition, each heap segment gets to specify a freelist (which
408 may be shared).
409
410 new function: scm_alloc_obj
411 new vars: scm_heap_table (replaces hplims)
412 scm_n_heap_segs (replaces (hpims_ind / 2))
413
414Thu Oct 27 12:57:02 1994 Aubrey Jaffer (jaffer@jacal)
415
416 From: Jerry D. Hedden <hedden@esdsdf.dnet.ge.com>
417 * ioext.c: conditional code for vms and version (3.6) of Aztec C.
418 * pi.scm ((e digits)): Modified 'bigpi' for slight speed
419 improvement. Added function to calculate digits of 'e'.
420
421Wed Oct 26 11:22:05 1994 Aubrey Jaffer (jaffer@jacal)
422
423 From: Gary Houston <ghouston@actrix.gen.nz>
424 * scl.c (round): Now rounds as described in R4RS.
425
426 * test.scm (test-inexact): test cases for round.
427
428Tue Oct 25 00:02:27 1994 Aubrey Jaffer (jaffer@jacal)
429
430 * sys.c (grow_throw lthrow dynthrow): now pass arrays, check
431 for adequate growth, and clear out register windows (on sparc).
432
433Mon Oct 24 01:05:34 1994 Aubrey Jaffer (jaffer@jacal)
434
435 * ioext.c (ttyname fileno): added.
436
437Sat Oct 22 12:12:57 1994 Aubrey Jaffer (jaffer@jacal)
438
439 * unix.c (symlink readlink lstat): added.
440
441 * scmfig.h repl.c sys.c (IO_EXTENSIONS): flag removed.
442
443 * ioext.c (read-line read-line! file-position, file-set-position
444 reopen-file open-pipe opendir readdir rewinddir closedir chdir
445 umask rename-file isatty? access chmod mkdir rmdir stat utime
446 raise): moved from "repl.c" and "sys.c".
447
448Fri Oct 21 21:19:13 1994 Aubrey Jaffer (jaffer@jacal)
449
450 From: Radey Shouman <shouman@ccwf.cc.utexas.edu>
451 * unif.c (ra2contig): now has a second parameter to indicate
452 whether copying is necessary or not. Eliminates gratuitous copy
453 by UNIFORM-ARRAY-READ! when called with a noncontiguous array.
454
455 (array_map): more liberal check on when ARRAY-MAP! can use
456 array-ified asubrs.
457
458Thu Oct 20 18:00:35 1994 Aubrey Jaffer (jaffer@jacal)
459
460 * sys.c (opendir readdir rewinddir closedir reopen-file): added
461 under IO_EXTENSIONS.
462
463Wed Oct 19 14:18:26 1994 Aubrey Jaffer (jaffer@jacal)
464
465 * eval.c (badargsp): added under ifndef RECKLESS to check @apply
466 and apply() arg counts.
467
468Tue Oct 18 00:02:10 1994 Aubrey Jaffer (jaffer@jacal)
469
470 * unix.c (mknod acct nice sync): added.

506 From: rshouman@hpcf.cc.utexas.edu (Radey Shouman)
507 Date: Mon, 29 Aug 1994 11:36:46 +0600
508 * unif.c: This is a large patch, but also a bit larger than it
509 appears -- I moved a few function definitions around to eliminate
510 gratuitous forward references.
511
512 * unif.c repl.c (raprin1): Combined print routine for arrays with
513 that for uves.
514
515 * unif.c (UNIFORM-VECTOR-READ! and -WRITE): work with general
516 arrays, by copying when necessary, renamed them to
517 UNIFORM-ARRAY-READ! and -WRITE.
518
519 * unif.c (ARRAY-CONTENTS): Generalized so that it returns a 1-d
520 array even when the stride in the last dimension is greater than
521 one, gave it an optional second argument STRICT, which makes it
522 behave as it did before, returning an array/vector only if the
523 contents are contiguous in memory.
524
525 * unif.c (ARRAY-CONTIGUOUS?) Eliminated. Instead, use
526 (lambda (ra) (array? (array-contents ra #t)))
527
528 * unif.c code.doc (ramapc): unrolls arrays mapping into one loop
529 if possible, to make this quick, changed the format of the array
530 CAR, now uses one bit to indicate that an array is contiguous --
531 this still allows a ridiculous number of dimensions.
532
533 * scm.h (DSUBRF): dsubrs are mapped directly, to allow this I
534 moved the typedef for dsubr and #define for DSUBRF to scm.h
535
536 * unif.c (ARRAY-MAP!) taught something about subrs, now most subrs
537 may be mapped without going through apply(), saving time and
538 reducing consing. +, -, *, /, =, <, <=, >, and >= are mapped
539 directly as special cases -- for uniform arrays this is nearly as
540 fast as the equivalent C, and doesnt' cons. I've made sure that
541 +, -, *, and / vectorize on the CRAY, this may be wasted effort
542 but the effort is not great.
543
544 * unif.c (ARRAY-COPY!) now copies many arrays of differing types
545 to each other without going through the aref/aset, e.g. float ->
546 double, double -> complex, integer -> float ... This should make
547 array type coercions for arithmetic faster.
548
549 * unif.c (TRANSPOSE-ARRAY) Added, which returns a shared array
550 that is the transpose of its first argument. I think this does
551 what an APL:TRANSPOSE would.
552
553 * unif.c (ENCLOSE-ARRAY) Added, this returns an array that looks
554 like an array of shared arrays, the difference being that the
555 shared arrays are not actually allocated until referenced.
556 Internally, the contents of an enclosed array is another array.
557 The main reason for this is to allow a reasonably efficient
558 implementation of APL:COMPRESS, EXPAND, and INDEXING. In order to
559 actually make an array of shared arrays, just use ARRAY-COPY!.
560
561 * unif.c (cvref): Created internal version of aref(), cvref() that
562 doesn't do error checking; Thus speeding things up. Profiling of
563 SCM running array code revealed that aref() was taking a
564 surprising fraction of the CPU time
565
566 TO DO:
567
568 The mechanism for looking up the vectorized functions is a little
569 kludgy, I was tempted to steal some of the CAR of the subr type to
570 encode an offset into a table of vectorized functions, but this
571 would make it more likely that dynamically loaded subrs lose thier
572 names.
573
574 It is almost possible to write APL:+ and friends now, it is just
575 necessary to figure out the appropriate type of the returned array
576 and allocate it, and to promote scalar arguments to arrays (with
577 increments 0).
578
579 This doesn't include vectorized REAL-PART, IMAG-PART,
580 MAKE-RECTANGULAR ...
581
582 I think some C support for APL:REDUCE and maybe INNER-PRODUCT will
583 be needed for a reasonably fast APL.scm
584
585 unif.c is getting quite big, time to split it up?
586
587
588Mon Sep 5 22:44:50 1994 Aubrey Jaffer (jaffer@jacal)
589
590 * Init.scm repl.c (quit): code was not using return values
591 correctly.

661Thu May 12 00:01:20 1994 Aubrey Jaffer (jaffer@jacal)
662
663 * Link.scm: Autoload for hobbit now does (provide 'hobbit). This
664 allows hobbit to know if it is self compiling (although reloads of
665 hobbit will not be quite right).
666 ((compile file . args)): removed.
667
668 * makefile.unix (proto.h): removed.
669
670 * Transcen.scm: compile-allnumbers HOBBIT declaration added.
671 Init.scm will now load compiled Transcen.o.
672
673 * scm.h: HOBBIT section removed.
674
675 * README (SLIB): Now strongly recommends getting SLIB and lists
676 ftp sites.

686
687 From: rshouman@chpc.utexas.edu (Radey Shouman)
688 * unif.c: no longer uses pointer comparisons in loops. Should
689 fix problems on 8086 processors.
690 * unif.c (make_sh_array): Fixes MAKE-SHARED-ARRAY so that shared
691 arrays with only 1 element in some direction may still be
692 ARRAY-CONTIGUOUS?
693 (uve_write uve_read): Fixes bug in UNIFORM-ARRAY-WRITE,
694 UNIFORM-ARRAY_READ!. Now they do the right thing for shared
695 bit-arrays not starting at the beginning of their contents vector.
696 (array_contents ARRAY-SIMPLE?): ARRAY-CONTENTS may now return a
697 shared, contiguous, 1-d array, instead of a vector, if the array
698 cannot access all of the contents vector. ARRAY-SIMPLE? removed.
699 (array-fill!): a replacement and generalization of
700 UNIFORM-VECTOR-FILL!.
701 (raequal): Combines with uve_equal(), providing also ARRAY-EQUAL?
702 ARRAY-EQUAL? is equivalent to EQUAL? if all its arguments are
703 uniform vectors or if all are arrays. It differs from EQUAL? in
704 that a shared, 1-d array may be ARRAY-EQUAL? to a uniform vector.
705 for example
706 (define sh (make-shared-array '#(0 1 2 3) list '(0 1))) ==> #1(0 1)
707 (equal? '#(0 1) sh) ==> #F
708 (array-equal? '#(0 1) sh) ==> #T

780 #-.
781
782 * repl.c (lreadr): Now calls out to Scheme function read:sharp

832 * makefile.acorn repl.c (set_erase): Port to acorn archimedes.
833 This uses Huw Rogers free unix function call library for the

846
847 From: fred@sce.carleton.ca (Fred J Kaudel)
848 * unif.c (ra_matchp ramapc): patch to unif.c avoids two problems
849 (K&R C does not allow initialization of "automatic" arrays or
850 structures). This was not use in 4d2 or previously, and the
851 following patch ensures that such initialization only occurs for
852 ANSI C compilers (Note that K&R C compilers need to explicitly
853 assign the values).
854
855Sat Dec 18 23:55:30 1993 (jaffer at jacal)
856
857 * scm.1 scm.doc (FEATURES): improved and updated manual page.

922 * scm.c config.h (TICKS ticks tick-interrupt): if TICKS is
923 #defined, ticks and tick-interrupt work like alarm and
924 alarm-interrupt, but with units of evaluation rather than units of
925 time.

1878 lessp(), greaterp(), lesseqp() and greatereqp(). In addition, I
1879 modified these routines and eqp() to allow for mixed arithmetic
1880 types.

2092
2093Mon Dec 2 11:37:11 1991 Aubrey Jaffer (jaffer at Ivan)
2094
2095 * patchlvl.h (PATCHLEVEL): 4

2097 * sys.c (gc_sweep): usaage of pclose() now conditional on unix.
2098
2099 * MANUAL (chdir): documented.
2100
2101 from T. Kurt Bond, Adminisoft, Inc. <tkb@MTNET2.WVNET.EDU>:
2102
2103 * repl.c sys.c (errno): VMS GNU C uses a special hack in <errno.h>
2104 to get the link-time attributes for the errno variable to match
2105 those the VMS C run-time library expects (it makes errno a
2106 preprocessor define so that the variable that the compiler sees
2107 has a special form that the assember then interprets), so if it is
2108 VMS and __GNUC__ is defined <errno.h> needs included.
2109
2110 * setjump.h (SETJUMP LONGJUMP): SETJUMP and LONGJUMP changed to
2111 setjump and longjump. The VMS linker is case-indifferent. VMS GNU
2112 C mangles variable names that have upper case letters in them to
2113 preserve their uniqueness.
2114
2115 * sys.c (iprint iprin1): Now inline putc loops instead of calls to
2116 fwrite for VMS. The VMS `fwrite' has been enhanced to work with
2117 VMS's Record Management Sevice, RMS. Part of this enhancement is
2118 to treat each call to `fwrite' as producing a separate record.
2119 This works fine if you are writing to a stream_LF file or an
2120 actual terminal screen, but if you are writing to a file that has
2121 implied carriage control (such as a batch log file, or a mailbox
2122 used for subprocess communication), which is a more common file
2123 organization for RMS, each call to `fwrite' has a newline appended
2124 to it. This causes much of the output to be incorrectly split
2125 across lines.
2126
2127 * vmsgcc.com: created.
2128
