ice-9/ChangeLog

   1 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
   2
   3         * boot-9.scm (error-catching-loop thunk): use a status variable to
   4         return the quit args.
   5         (scm-style-repl): call -quit, passing return value from
   6         error-catching-repl.  Make -quit return its args.
   7         stand-along-repl: comment out, since it seems unused.
   8         (top-repl): convert the value returned by scm-style-repl to
   9         an integer and return it.
  10
  11         (error-catching-loop thunk): discard trailing junk after a (quit).
  12
  13 Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  14
  15         * boot-9.scm: Removed the old printer code.
  16
  17         * r4rs.scm (apply, call-with-current-continuation): Added comment
  18         explaining why apply and call/cc need to be closures.
  19
  20         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
  21         Removed. These definitions are already present in r4rs.scm.
  22
  23         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
  24         stack before printing traced frames; Re-enable trace flag at end
  25         of handlers.
  26
  27 Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  28
  29         * debug.scm: Add hook for reset of trace level at abort.
  30
  31         * boot-9.scm (run-hooks): New procedure.
  32         (add-hooks!): New macro.
  33         Change hooks to use these functions.
  34
  35 *       * debug.scm: *Warning* This feature is a bit premature.  I add
  36         it anyway because 1. it is very useful, and, 2. you can start
  37         making it less premature by complaining to me and by modifying
  38         the source! :-)
  39         (trace): Given one or more procedure objects, trace each one.
  40         Given no arguments, show all traced procedures.
  41         (untrace): Given one or more procedure objects, untrace each one.
  42         Given no arguments, untrace all traced procedures.  The tracing in
  43         Guile have an advantage to most other systems: We don't create new
  44         procedure objects, but mark the procedure objects themselves.
  45         This means that also anonymous and internal procedures can be
  46         traced.
  47
  48         * boot-9.scm (error-catching-loop): Added handling of apply-frame
  49         and exit-frame exceptions.
  50
  51 *       * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
  52         (set-repl-prompt!): Setter for repl prompt.
  53         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
  54         string, display it; if prompt is a thunk, call it and display its
  55         result; otherwise display "> ".
  56         (Change suggested by Roland Orre <orre@nada.kth.se>.)
  57
  58         * r4rs.scm (%load-verbosely): Reverted change to
  59         `module-defined?', since the module system isn't bootstrapped when
  60         we load r4rs.scm.  This is just a temporary fix to make the
  61         repository version runnable.
  62
  63 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  64
  65         * boot-9.scm: Removed the enabling of debug evaluator and
  66         recording of source code positions.  This was placed there for our
  67         convenience, but it has already sneaked into the distribution
  68         once... so we'd better add this in our local copies instead when
  69         we need it.  (These options are normally enabled at the end of
  70         boot-9.scm when loading the debug module.)
  71
  72 Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>
  73
  74         * boot-9.scm (module-defined?): New function.
  75         (macroexpand-1, macroexpand): Use local-ref instead of defined?
  76         and eval.
  77         * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
  78         "defined?".
  79         * slib.scm (defined?): New function to take the place of the
  80         builtin "defined?".  It allways examines the slib module.
  81
  82 Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  83
  84         * configure.in: Added AM_MAINTAINER_MODE
  85
  86 Sat Feb 15 04:51:20 1997  Gary Houston  <ghouston@actrix.gen.nz>
  87
  88         * boot-9.scm (read-sharp): define directly, don't go through a
  89         %read-sharp layer.
  90
  91 Tue Feb 11 08:45:48 1997  Gary Houston  <ghouston@actrix.gen.nz>
  92
  93         * boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
  94         uniform-vector-set1! which doesn't exist.
  95
  96 Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>
  97
  98         * boot-9.scm (backtrace): Removed.  (A C version now exists in
  99         backtrace.c.)
 100
 101 Fri Jan 24 06:05:36 1997  Gary Houston  <ghouston@actrix.gen.nz>
 102
 103         * boot-9.scm (read-line!, read-delimited!, read-delimited,
 104         read-line): new procedures, see libguile/ChangeLog.
 105
 106 Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 107
 108         Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.
 109
 110         * boot-9.scm (split-c-module-name, convert-c-registered-modules,
 111         init-dynamic-module, dynamic-maybe-call,
 112         find-and-link-dynamic-module, link-dynamic-module,
 113         try-module-dynamic-link, registered-modules): New definitions for
 114         dynamic linking of modules.
 115         (resolve-module): Try to dynamically link the requested module
 116         after failing to load it as Scheme code.
 117
 118 Wed Jan  8 05:50:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 119
 120         * boot-9.scm (getservbyport, getservbyname): remove stray %.
 121
 122 Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>
 123
 124         * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
 125         that's what it is.
 126
 127         * lineio.scm (make-line-buffering-input-port): Properly test for
 128         the case of an empty buffer list.  The old code assumed that '()
 129         was false.
 130
 131 Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>
 132
 133 *       * boot-9.scm (use-modules): New macro (from Marius Vollmer).
 134         (use-modules <module name> ...) Put the the modules named by
 135         <module name> ... on the use list of the current module.
 136
 137 Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>
 138
 139         * boot-9.scm (error-catching-loop): Remove message saying that
 140         typing "$" will put you in the debugger.  This isn't implemented
 141         yet.
 142
 143 Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
 144
 145         * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
 146         been fixed, so this function is superfluous.
 147         (transform-usage-lambda): Use delq!, not delq-all!.
 148
 149 Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 150
 151         * boot-9.scm (resolve-module): New optional parameter that
 152         controls whether autoloading is attempted or not. Default is #t.
 153         (process-define-module): Don't autoload the defined module.
 154         (try-module-autoload): Don't autoload the directory modules.
 155
 156         * boot-9.scm (process-define-module): Ensure that the-scm-module
 157         is last in the `uses' list to allow shadowing builtin
 158         bindings. All :use-module options are added in the order they
 159         appear in the arguments but before anything already on the list
 160         (such as the-scm-module).
 161
 162 Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
 163
 164         * slib.scm (slib-parent-dir): throw error if #f returned from
 165         %search-load-path.
 166
 167 Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>
 168
 169         * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
 170         * Makefile.am, aclocal.m4: New files.
 171         * configure.in: Updated for Automake.
 172
 173 Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 174
 175         * boot-9.scm (macroexpand-1, macroexpand), slib.scm
 176         (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
 177         function, use it accordingly.
 178
 179 Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>
 180
 181         It's an "eval closure", not an "eval thunk."  A thunk is a
 182         function of no arguments.
 183         * boot-9.scm (module-type): Rename module field.
 184         (make-module, eval-in-module, make-root-module,
 185         set-current-module): Uses changed.
 186         (module-eval-closure, set-module-eval-closure!,
 187         root-module-closure): Renamed from module-eval-thunk,
 188         set-module-eval-thunk!, root-module-thunk.
 189         (set-current-module): Change uses of *top-level-lookup-thunk* to
 190         *top-level-eval-closure*.
 191
 192 Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 193
 194         * slib.scm (slib-parent-dir): Use string-length, not length.
 195         (Thanks to Bernard Urban.)
 196
 197 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 198
 199         * boot-9.scm: The debugging evaluator and recording of positions
 200         aren't enabled by default any longer (they are switched on in
 201         debug.scm).  But during development we want to have them also
 202         *inside* boot-9.scm.  Therefore, two lines are added at the
 203         beginning of boot-9.scm to enable these.
 204
 205         Call `provide' so that `records' are included among the
 206         `*features*'.
 207
 208         The scheme for saving the stack has been adjusted: save-stack is
 209         now commonly available for saving the stack.  Calling `save-stack'
 210         sets a flag `stack-saved?' which prevents overwriting the stack.
 211         `stack-saved?' is reset at `abort'.
 212
 213         Spelling correction: seperate --> separate.
 214
 215         Removed `:'s that had creeped into some comments.
 216
 217         The repl now doesn't print #<unspecified> results any longer
 218         If the user wants to see this, he can do
 219         (assert-repl-print-unspecified #t) in his startup file.
 220
 221         The user now gets a friendly message instead of a backtrace at
 222         error.
 223
 224         Added `before-read-hook'.
 225
 226         Load module (ice-9 emacs) if option `-e' was specified.
 227
 228         (provide): New function.
 229
 230         (error): Save stack at entry, so that Guile entrails won't show up
 231         in backtraces.
 232
 233         (backtrace): New function.
 234
 235         (save-stack): Can now take arbitrary number of stack narrowing
 236         specifier pairs.  The first specifier in a pair controls inner
 237         border, the second the outer border.  A number means cut that
 238         number of frames, a procedure object means cut until that object
 239         is found in operator position in a frame.
 240
 241         * debug.scm: Enable debugging evaluator and recording of positions
 242         by default.
 243
 244         * slib.scm (slib:load): Adapt to the new behavior of
 245         primitive-load: It doesn't any longer try both with and without
 246         ".scm" extension.  (We don't want to use %search-load-path here.)
 247
 248         (implementation-vicinity): New function.  slib requires it
 249
 250         (library-vicinity): Updated.
 251
 252         Load "require.scm" in the library-vicinity.
 253
 254         (install-require-vicinity, install-require-module): New functions.
 255
 256 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
 257
 258         * boot-9.scm (load-from-path): New function.
 259
 260         * boot-9.scm (try-load, basic-try-load, try-load-module,
 261         try-load): Deleted.  I don't think they're being used.
 262
 263         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
 264         so they'll get distributed.
 265
 266         Get Guile to be a little less chatty by default.  The new user
 267         should see as little clutter as possible.
 268         * r4rs.scm (%load-verbosely): Make this #f by default.
 269         * boot-9.scm (scm-repl-verbose): Make this #f by default.
 270         (scm-style-repl): Don't run 'pk' on the value passed to quit.
 271
 272         * r4rs.scm: New file.
 273         * boot-9.scm: Load r4rs.scm, first thing.
 274         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
 275         open-output-file, open-io-file, close-input-port,
 276         close-output-port, close-io-port, call-with-input-file,
 277         call-with-output-file, with-input-from-port, with-output-to-port,
 278         with-error-to-port, with-input-from-file, with-output-to-file,
 279         with-error-to-file, with-input-from-string, with-output-to-string,
 280         with-error-to-string, the-eof-object): Definitions moved to
 281         r4rs.scm.  Not all of them are R4RS, but those that are use those
 282         that are not.
 283         (load, %load-verbosely, %load-announce): Moved, along with code to
 284         set %load-hook, to r4rs.scm.
 285
 286         * test.scm: New file.
 287
 288         * boot-9.scm (integer?): Definition deleted, in favor of the one
 289         present in libguile (which used to be called int?).  I have no
 290         idea why integer? didn't just call int? to begin with.
 291
 292         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
 293         =?, >?, and >=? deleted; they're defined that way by libguile now.
 294
 295         * boot-9.scm (load): Simplified; primitive-load does most of this
 296         work now.
 297         (%load-announce-win): Removed; no longer used.  Set %load-hook to
 298         call %load-announce.
 299
 300 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
 301
 302         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
 303         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
 304         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
 305         components.
 306         (file-is-directory?): use stat:type.
 307
 308 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
 309
 310         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
 311         that's now taken care of in libguile, and in a way compatible with
 312         SCSH (which this isn't).
 313
 314 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 315
 316         * boot-9.scm: Formatting tweaks.
 317
 318 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 319
 320         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
 321         after-error-hook, before-backtrace-hook and after-backtrace-hook
 322         to the error handler.  E.g.: fancy emacs support could plug into
 323         these.
 324         (save-stack): New function.  The stack is now made differently
 325         depending on the stack id.  (The motivation is to make a better
 326         choice regarding what stack frames to present to the user.)
 327         (error-catching-loop): Stack handling code moved outside into
 328         save-stack.
 329
 330 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
 331
 332         * Makefile.in (scm_files): add expect.scm.
 333
 334         * expect.scm: new file ported from guile-iii.
 335
 336         * boot-9.scm: remove handle-system-error, after moving the code into
 337         error-catching-loop.
 338         Don't set 'throw-handler-default property on error keys.
 339         Just interpret (almost) any throw with 4 args as an error throw.
 340         Delete some try-load stuff that was already commented out.
 341
 342         Second thoughts, keep handle-system-error but call it from
 343         error-catching-loop.
 344
 345 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
 346
 347         * boot-9.scm: Doc fixes.
 348         (make-module): Rework for readability.
 349         (make-root-module, make-scm-module): USES argument to make-module
 350         should be '(), not #f.
 351
 352         * boot-9.scm (try-load): %sys-load-path has been renamed to
 353         primitive-load-path; adjust call here.
 354
 355 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 356
 357         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
 358         the stack to the correct place: when it is decided to generate an
 359         error-signal.
 360
 361 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 362
 363         * boot-9.scm (error-catching-loop, signal-handler,
 364         handle-system-error): Backtracing now works for signals aswell;
 365         Backtracing mechanism can now identify the stack root created by
 366         start-stack so that the user isn't exposed to system stack frames.
 367
 368 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 369
 370         * Makefile.in: Added threads.scm.
 371
 372 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 373
 374         * debug.scm (make-enable, make-disable): Simplified.
 375
 376         * boot-9.scm: Renamed %%throw-handler-default -->
 377         throw-handler-default.
 378         ((handle-system-error key . arg-list)): Changed the way errors are
 379         reported.
 380         ((scm-style-repl)): Wrap up the call to eval in a start-stack
 381         acro.
 382         ((error-catching-loop thunk)): Introduce a lazy-catch into

 385 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 386
 387         * mapping.scm (hash-table-mapping): Explicitly request that
 388         make-vector fill new vectors with '(); this will make it easier to
 389         port Guile Scheme code to other Schemes.
 390         * boot-9.scm (make-print-style, make-print-table): Same.
 391
 392 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
 393
 394         * boot-9.scm (load): rewritten again.
 395         Append "." to the default %load-path.
 396         (feature?): new function: checks for a symbol in the features list.
 397         (module-local-variable): remove apparently useless (caddr (list m v
 398         ...))
 399         (%load-announce): minor formatting change.
 400         (file-exists?): use access? if posix is featured.
 401         (file-is-directory?): use stat if i/o-extensions is featured.
 402         (try-module-autoload module-name): use file-exists? before
 403         file-is-directory?
 404
 405 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
 406
 407         * boot-9.scm: Added conditional loading of threads.scm.
 408
 409         * threads.scm: New file.  Modified from the Cygnus-r0.3
 410         distribution.
 411
 412         * boot-9.scm (error-catching-loop): Added handling of key
 413         `switch-repl'.
 414
 415         * boot-9.scm: Name change %%bad-throw --> bad-throw.
 416
 417 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 418
 419         * boot-9.scm (make-record-type, record-constructor): Don't assume
 420         the empty list is false when parsing the argument list.
 421
 422 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 423
 424         * boot-9.scm (signal-handler): Clean up logic.
 425
 426         * boot-9.scm (load): Assume %load-path is always bound.
 427
 428 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 429
 430         * boot-9.scm (error): replace another throw with scm-error.  Throw
 431         to 'misc-error instead of 'error (no need to distinguish these.)
 432         Don't set up 'error as a key.
 433         Set up regex-error as a key, if regex is available.
 434         (signal-handler): use scm-error, not throw.
 435
 436         (%try-load, try-load-with-path, %load, load-with-path,
 437         basic-try-load-with-path, basic-load-with-path,
 438         try-load-module-with-path,load-module-with-path): deleted, since
 439         they seem redundant.
 440         (try-load): define using %try-load, not try-load-with-path.
 441         (load): rewritten.  load tries to open the file directly and
 442         with a .scm extension before searching the library directories
 443         (should "." be added to %load-path?  then load could still open
 444         directly files starting with "/").
 445         (try-module-autoload): use load, not load-with-path.
 446         (%load-indent): deleted, -2 was causing errors.
 447
 448         (%read-sharp): use port-line, not line-number.
 449
 450 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 451
 452         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
 453         straightforward to provide the equivalent functionality using
 454         (catch #t ...), so there's no need for the extra complexity.  2)
 455         Outside the context of a read-eval-print loop (which Guile should
 456         not require) it's not clear we should do anything more complicated
 457         than print an error and exit; the user or REPL can establish
 458         something better if it wants.  3) In that case, it's much more
 459         robust to just do it in the C code.
 460
 461 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
 462
 463         * boot-9.scm (%try-load): define using primitive-load.  Previously
 464         %try-load itself was the primitive.
 465         (load-with-path): use scm-error instead of %load-announce-lossage.
 466         Errors are thrown to 'misc-error instead of 'could-not-load.
 467         (%load-announce-lossage): deleted.
 468
 469 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
 470
 471         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
 472         (make-record-type type-name fields): Temporarily remove support
 473         for printing of records (not possible yet with C printer).
 474
 475 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
 476
 477         * boot-9.scm (file-exists?, file-is-directory): catch only
 478         system-error, not every kind of error.
 479         (scm-error): new procedure.
 480
 481 Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 482
 483         * boot-9.scm: Formatting tweaks.
 484
 485 Wed Sep 18 09:07:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 486
 487         * boot-9.scm (%%handle-system-error key): remove the code for
 488         SCM-style errors.  handle the case that an unexpected number
 489         of args are supplied.
 490         (%%system-errors): removed.
 491         (error): redefine using a throw with key and 4 args.
 492         ('error): associate 'error, 'error-signal keys with
 493         %%handle-system-error.
 494         (%%default-error-handler): removed.
 495         (signal-handler): throw with 4 args and use the error-signal key.
 496         Create an error message instead of using numerical codes.
 497         (%%bad-throw): call error instead of throw if key not found.
 498
 499 Tue Sep 17 04:11:28 1996  Gary Houston  <ghouston@actrix.gen.nz>
 500
 501         * boot-9.scm: initialize new error keys (see libguile/ChangeLog).
 502         (%%handle-system-error key): check subr is not #f before printing.
 503         Recognize %s (embed an argument using "display") and
 504         %S (embed an argument using "write").
 505
 506 Sun Sep 15 03:55:35 1996  Gary Houston  <ghouston@actrix.gen.nz>
 507
 508         * boot-9.scm (%%handle-system-error key): set args and rest to
 509         the empty list if they are #f.
 510         Initialize out-of-range as an error key.
 511
 512 Sat Sep 14 03:41:15 1996  Gary Houston  <ghouston@actrix.gen.nz>
 513
 514         * PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.
 515
 516         * boot-9.scm: remove leading %% from references to '%%system-error.
 517         (%%handle-system-error): don't pass all the thrown arguments when
 518         aborting, just the key and subr.
 519         Remove the code to "Install default handlers for built-in errors."
 520         Remove the definition of the syserror procedure.
 521         Associate 'numerical-overflow with default handler.
 522
 523 Fri Sep 13 04:58:11 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 524
 525         * boot-9.scm: Name change: value-ref --> local-ref
 526         resolved-ref --> nested-ref  Motivation: conformance to the other
 527         dictionary operators: list-ref operates on list, vector-ref
 528         operates on vector, nested-ref operates on nested namespace,
 529         local-ref operates on the local nested namespace.
 530
 531 Sat Sep  7 06:44:47 1996  Gary Houston  <ghouston@actrix.gen.nz>
 532
 533         * boot-9.scm (%%handle-system-error): recognise errors thrown
 534         by lgh-error (fill-message etc.)
 535         (fill-message): check first whether args is null.
 536         (fill-message): bug fix and check that args is a list.

 538 Thu Sep  5 11:33:41 1996  Jim Blandy  <jimb@floss.cyclic.com>
 539
 540         * boot-9.scm: %load-path is initialized in C code now.
 541         (implementation-vicinity, parse-path): Deleted, along with code to
 542         initialize %load-path.
 543
 544         * boot-9.scm (in-vicinity): If the vicinity doesn't end with a
 545         "/", use one to separate it from the file.
 546
 547 Thu Aug 29 23:05:11 1996  Thomas Morgan  <tmorgan@gnu.ai.mit.edu>
 548
 549         * boot-9.scm (%load-path): Add the site directory.
 550         Add the directory named after the version number.
 551         Prepend the version number to the other directories in the path.
 552         Simplify by mapping the common prefix onto each item.
 553         * Makefile.in (datadir, pkgdatadir, pkgverdatadir, subpkgdatadir,
 554         sitedatadir): New definitions.
 555         (libparent, libdir, install_path): Replaced by above.

 561
 562         Don't use the PLUGIN system to gather information for the
 563         Makefile's distribution and installation targets; just put it all
 564         in the Makefile directly.
 565         * PLUGIN/this.configure (scm_files, aux_files): Remove sections
 566         for these.
 567         * configure.in: Remove code that gets and substitutes scm_files and
 568         aux_files.

 605         (manifest): Deleted.
 606         * PLUGIN/this.configure (aux_files): Removed PLUGIN; it's a
