[bpt/guile.git] / ice-9 / ChangeLog

2005-06-05  Marius Vollmer  <mvo@zagadka.de>

	* boot-9.scm (substring-fill!): New, for compatability.

2005-04-23  Kevin Ryde  <user42@zip.com.au>

	* boot-9.scm (make-list): Moved to C code in list.c

2005-04-14  Kevin Ryde  <user42@zip.com.au>

	* boot-9.scm (1+, 1-): Moved to numbers.c.

2005-03-08  Kevin Ryde  <user42@zip.com.au>

	* slib.scm (*features*): Remove 'random, need to use the slib code for
	that module since guile doesn't provide `random:chunk'.

2005-02-12  Rob Browning  <rlb@defaultvalue.org>

	* boot-9.scm (%cond-expand-features): add srfi-55.
	(require-extension): add require-extension macro for srfi-55.

2005-01-29  Kevin Ryde  <user42@zip.com.au>

	* regex.scm (regexp-quote): Use string-for-each, now that function is
	in the core.

2005-01-28  Kevin Ryde  <user42@zip.com.au>

	* boot-9.scm (while): Remove the unquote from do, it breaks with ice-9
	syncase.  Reported by Pach Roman.

2005-01-10  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* arrays.scm, deprecated.scm (uniform-vector-fill!,
	make-uniform-vector, make-uniform-array, list->uniform-vector):
	Moved from arrays.scm to deprecated.scm.
	* arrays.scm, boot-9.scm (array-dimensions): Moved from arrays.scm
	to boo-9.scm.
	* Makefile.am (ice9_sources): Removed arrays.scm.
	
2005-01-02  Marius Vollmer  <mvo@zagadka.de>

	* arrays.scm (uniform-vector-fill!, make-uniform-vector,
	make-uniform-array,list->uniform-array): Deprecated for real.

2004-12-29  Marius Vollmer  <mvo@zagadka.de>

	* arrays.scm (make-array, list->array): Removed.
	(uniform-vector-fill!): Prepared to be deprecated.

2004-12-22  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* boot-9.scm (module-make-local-var!): When creating a new
	variable, initialize it to the value of any imported variable with
	the given name.  This allows code like (define round round) to
	work as expected.

        From Antoine Mathys <tonigonenstein@users.sourceforge.net>:

	* popen.scm: Support bidirectional communication by making
	open-pipe support OPEN_BOTH as second argument and in that case
	return a soft input-output port which uses two pipes internally.
	Provide open-pipe* to execute programs without using the shell
	(and actually base open-pipe on it) and the obvious
	open-input-output-pipe.

2004-12-14  Kevin Ryde  <user42@zip.com.au>

	* boot-9.scm: (string-any, string-every): Use a scheme wrapper around
	the C code so for the final call to the predicate procedure is a tail
	call, per SRFI-13 spec.

2004-12-01  mvo  <mvo@zagadka.de>

	* boot-9.scm (app, %app): Renamed former to the latter.
	Previously, 'app' was reserved in every module.  Now '%app' is
	reserved, which is slightly better.  The real fix is to not use
	'local-ref' etc to find modules.  Changed all uses.
	* syncase.scm: Changed 'app' to '%app'.

2004-11-12  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* arrays.scm: Do not use prototypes, use creator functions.

2004-11-10  Marius Vollmer  <mvo@zagadka.de>

	* arrays.scm (uniform-vector-read!, uniform-vector-write):
	Removed.

2004-11-05  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* boot-9.scm: Do not add "." to %load-path. 'load' will still be
	able to load files in the current directory, but 'use-modules' etc
	will not.

2004-10-29  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* arrays.scm: Do not install read-hash procedure for reading
	arrays, this is done in libguile now.

2004-10-27  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* arrays.scm (uniform-vector?, uniform-vector-set!): Removed, now
	provided by libguile.

2004-10-26  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* boot-9.scm: Added srfi-4 to cond-expand features.

2004-10-18  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* format.scm (format:obj->str): Simplified considerably by using
	object->string or display instead of implementing our own printer.
	Handle format:read-proof here.  Unreadable objects are recognized
	by their "#<" prefix instead of by being unknown to the custom
	printer (which would treat keywords as unprintable, for example).
	(format:iobj->str): Removed.
	
2004-10-04  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* boot-9.scm (symbol->keyword, keyword->symbol): Removed, they are
	now implemented in C.

2004-09-26  Kevin Ryde  <user42@zip.com.au>

	* optargs.scm (let-optional-template, let-keywords-template): Change
	"(begin body)" to "(let () body)" for empty bindings, since the former
	allows "internal defines" in body leak out to the surrounding
	environment.

2004-09-23  Marius Vollmer  <mvo@zagadka.de>

	* boot-9.scm (handle-system-error): Pass rest argument to
	display-backtrace for wrong-type-arg and out-of-range errors so
	that the bad value gets highlighted.

2004-09-04  Kevin Ryde  <user42@zip.com.au>

	* streams.scm (stream-for-each-many): Correction, should recurse into
	itself, not stream-for-each-one.

	* time.scm (time-proc): Make result inexact, since format ~f doesn't
	support fractions currently.

2004-09-08  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* boot-9.scm (expt): Only call integer-expt for an exact integer
	exponent, not for an inexact integer one.  Also, let integer-expt
	handle negative exponents instead of doing it here.

2004-09-02  Kevin Ryde  <user42@zip.com.au>

	* format.scm (format:out): Ignore excess arguments, per common lisp.

	* format.scm (format:out-num-padded): Print "+" on 0 under @ modifier.

2004-08-27  Kevin Ryde  <user42@zip.com.au>

	* regex.scm (regexp-quote): [ and | must be quoted.  Quote ( ) { + ?
	using char class [(] etc since \( in fact makes them become special in
	regexp/basic.

2004-08-25  Kevin Ryde  <user42@zip.com.au>

	* and-let-star.scm (and-let*): Give #t for an empty body, per srfi-2
	spec, previously came out as an empty (begin).

2004-08-25  Marius Vollmer  <mvo@zagadka.de>

	* boot-9.scm (%cond-expand-features): Added srfi-13 and srfi-14.

2004-08-20  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* debugger/utils.scm (display-source): Use unmemoize-expr instead
	of unmemoize.
	(write-frame-short/expression): Likewise.

2004-08-18  Kevin Ryde  <user42@zip.com.au>

	* and-let-star.scm: Add cond-expand-provide srfi-2, since this module
	provides that feature.
	* receive.scm: Add cond-expand-provide srfi-8, since this module
	provides that feature.

2004-08-09  Marius Vollmer  <mvo@zagadka.de>

	From Matthias Koeppe.  Thanks!
	
	* pretty-print.scm (generic-write): In the local procedure `wr', use
	object->string to print all data (except for the reader macros),
	rather than implementing an own printer.  The user-visible
	difference is that procedures and control characters like #\tab
        are now printed in the same way as by `write'.

2004-08-09  Kevin Ryde  <user42@zip.com.au>

	* slib.scm (*features*): Remove array and array-for-each, core
	definitions are insufficient for latest slib.
	(t, nil): New constants slib says are supposed to exist.
	(call-with-open-ports, browse-url): New functions for latest slib.
	Implementations taken from Template.scm (public domain).
	(open-file): Extend core definition to accept symbols for the mode,
	required by latest slib.
	(delete-file): Replace core definition with version returning #t/#f as
	per slib spec.
	(system): Mark as #:replace to suppress override warning, use new
	style "(@ (guile) system)" to call core function.

2004-05-25  Matthias Koeppe  <mkoeppe@mail.math.uni-magdeburg.de>

	* format.scm: Remove the arbitrary limit of 100 iterations for the
	~{...~} control structure.

2004-07-10  Kevin Ryde  <user42@zip.com.au>

	* and-let-star.scm (and-let*): Remove unused variable "val".
	* pretty-print.scm (read-macro-prefix): Remove unused variable "tail".

	* boot-9.scm (%cond-expand-features): Add srfi-6 which is in the core.

	* safe-r5rs.scm (re-export): Uncomment numerator, denominator,
	rationalize, since they now exist.
	
2004-07-05  Kevin Ryde  <user42@zip.com.au>

	* slib.scm (system): Correction to redefinition, now guile is stricter
	about when a define binding comes into existance.

2004-05-29  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* boot-9.scm: Reordered definitions such that macro definitions
	preceed their first usage.  Include and define deprecated stuff
	late in the file to have a better change of detecting accidental
	uses of deprecated definitions. Further, unified the layout a
	little and grouped definitions more cleanly into topics.

2004-05-24  Marius Vollmer  <mvo@zagadka.de>

	* history.scm (use-value-history): Use resolve-interface instead
	of resolve-module so that only the exported bindings are searched.
	(save-value-history): Export the newly defined variable.  Reported
	by Wolfgang Jaehrling.
	
2004-05-04  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* boot-9.scm (resolve-module): Always start searching from the
	root module.  This will allow the C equivalent scm_resolve_module
	to work, independent of what the current module is.

2004-02-18  Marius Vollmer  <mvo@zagadka.de>

	* boot-9.scm (top-repl): Make the (guile-user) module use the
	(ice-9 r5rs) module.

2004-02-12  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* boot-9.scm (module-map): Renamed hash-map -> hash-map->list.

2004-02-09  Neil Jerram  <neil@ossau.uklinux.net>

	* debugger/trap-hooks.scm (debug-hook-membership): New, exported.

	* debugger/commands.scm (debug-trap-hooks): New, exported.

2004-02-08  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* debugger/breakpoints/Makefile.am (TAGS_FILES),
	debugger/Makefile.am (TAGS_FILES), Makefile.am (TAGS_FILES): Use
	this variable instead of ETAGS_ARGS so that TAGS can be built
	using separate build directory.

2004-01-20  Neil Jerram  <neil@ossau.uklinux.net>

	* boot-9.scm (error-catching-loop): Back out 2003-11-19 change to
	lazy-handler-dispatch lookup.

2004-01-12  Marius Vollmer  <mvo@zagadka.de>

	* mapping.scm: Use '#:' prefix for keywords instead of ':'.
	Thanks to Richard Todd!

2004-01-11  Kevin Ryde  <user42@zip.com.au>

	* slib.scm (system): New function, giving an exit code return in
	accordance with slib spec.
	
	Revert this, it breaks test-suite/tests/r5rs_pitfalls.test where
	false-if-exception is used within syntax-rules.  (Suspect syntax-rules
	ought to support this sort of thing, but it doesn't right now.)
	* boot-9.scm (false-if-exception): Unquote catch and lambda, so as not
	to depend on expansion environment.

2004-01-07  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* boot-9.scm (with-fluids): Use with-fluid* when only one fluid is
	being set.

2004-01-07  Kevin Ryde  <user42@zip.com.au>

	* q.scm (q-pop!): Should be "null?" not "not" for end-of-list.
	Reported by Richard Todd.

2004-01-04  Kevin Ryde  <user42@zip.com.au>

	* boot-9.scm (false-if-exception): Unquote catch and lambda, so as not
	to depend on expansion environment.

	* slib.scm (-1+, <?, <=?, =?, >?, >=?): Define as aliases for 1-, <,
	<=, =, >, >= respectively, required by slib 'rev2-procedures but no
	longer in the guile core.

2003-11-19  Neil Jerram  <neil@ossau.uklinux.net>

	* boot-9.scm (error-catching-loop): Defer lookup of
	lazy-handler-dispatch.

	* debugger.scm: Change ui-* calls to gds-*.
	(debug-on-error): Debug if throw key is in specified syms, not if
	it isn't!  Also throw 'abort after debugging, so as to skip the
	REPL's backtrace.

	* debugger/behaviour.scm (*trap*): New variable, stores trap type.
	(before-enter-frame-hook, before-apply-frame-hook,
	before-exit-frame-hook): Set here.
	(debug-if-flag-set): Passed into flags on debug-stack call.
	(at-step, at-next): Changed to debug at frame exit points as well.

	* debugger/utils.scm: Big comment added.

2003-10-30  Neil Jerram  <neil@ossau.uklinux.net>

	debug immediately on connection.
	(ui-eval): Handle exceptions during read and evaluation.

	* debugger.scm (debug-on-error, default-default-lazy-handler):
	Remove an unnecessary level of indirection in calling lazy
	handler.

2003-10-12  Marius Vollmer  <mvo@zagadka.de>

	* ftw.scm (directory-files): Close dir-stream when done.  Thanks
	to Paul Jarc!

2003-10-09  Kevin Ryde  <user42@zip.com.au>

	* poe.scm (funcq-assoc): Rewrite, don't assume '() is false, and
	actually traverse the given alist.
	
2003-10-06  Neil Jerram  <neil@ossau.uklinux.net>

	* debugger/ui-client.scm (handle-instruction): Add evaluation

	* debugger/ui-client.scm (ui-disable-async-thread,
	ui-continue-async-thread, start-async-ui-thread): New.
	(ui-command-loop): Call ui-disable-async-thread and
	ui-continue-async-thread.
	(handle-instruction): Read terminating newline char so it doesn't
	cause following select to pop immediately.

2003-09-25  Neil Jerram  <neil@ossau.uklinux.net>

	* debugger/ui-client.scm, debugger/ui-server.scm: New (work in
	progress on new debugging front end).

2003-09-24  Neil Jerram  <neil@ossau.uklinux.net>

	* debugger.scm (default-default-lazy-handler, debug-on-error):
	New.

	* debugger/behaviour.scm (debug-if-flag-set): Display debug entry
	messages through (debugger-output-port).

	(trace-here): Trace through (debugger-output-port).

	* debugger/commands.scm (evaluate): If supplied expression is a

2003-09-19  Kevin Ryde  <user42@zip.com.au>

	* popen.scm (open-process): Correction to previous fdes closing
	change, need to watch out for stdin==stderr or stdout==stderr.

2003-09-15  Marius Vollmer  <mvo@zagadka.de>

	reentrant.  No mutex is necessary.  Thanks to Clinton Ebadi!

2003-09-13  Kevin Ryde  <user42@zip.com.au>

	* boot-9.scm (file-exists?): Use stat rather than access?, so as to
	follow the effective UID/GID not the real ID.  file-exists? is
	normally used as a prelude to opening or some other operation, and
	it's the effective ID which will apply there.  Emacs file-exists-p
	uses stat, presumably for the the same reason.

2003-09-12  Marius Vollmer  <mvo@zagadka.de>

	* boot-9.scm (make-autoload-interface): Use a proper hashtable as
	the obarray, not an empty vector.
	(make-module): Always construct a hashtable for the obarray, even
	for empty ones.

	* format.scm (format:error): Use 'format:format' instead of
	'format' since the latter will lock the mutex again that we have
	already locked.

	break and continue associate to their loop even when recursing.

2003-08-14  Kevin Ryde  <user42@zip.com.au>

	* boot-9.scm (while): Rewrite, continue as proper escape, break
	without return value, break and continue new for each while form,
	don't depend on bindings in expansion environment.

	* popen.scm (open-process): Close input-fdes, output-fdes and
	error-fdes after duping them to 0, 1 and 2.

2003-06-19  Kevin Ryde  <user42@zip.com.au>

	* threads.scm (parallel): For no forms, use `(values)' not `(begin)'.

2003-05-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* boot-9.scm (make-autoload-interface): Added missing quote around
	vector constant.

2003-05-20  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* deprecated.scm (list*): Added.

2003-05-10  Kevin Ryde  <user42@zip.com.au>

	call-with-input-file, to close ports when done.

2003-05-03  Marius Vollmer  <mvo@zagadka.de>

	* gap-buffer.scm (point++n!, point+-n!): Use substring-move!
	instead of substring-move-left! or substring-move-right!.  Thanks
	to Kevin Ryde.

	* deprecated.scm (substring-move-left!, substring-move-right!):
	New.

	* boot-9.scm (display-usage-report): Use keyword->symbol instead
	of keyword-symbol, which doesn't exist.  Thanks to Kevin Ryde.

	* hcons.scm (hashq-cons-get-handle): Pass only the expected four
	arguments to hashx-get-handle.  Thanks to Kevin Ryde!

	* lineio.scm (make-line-buffering-input-port) Pass 0 as second
	argument to string-ref.  Thanks to Kevin Ryde!

2003-04-25  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* serialize.scm: New file.

2003-04-24  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* threads.scm (n-for-each-par-map): New procedure.

2003-03-26  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* deprecated.scm: New file, to collect deprecated things.
	* Makefile.am (ice9_sources): Added.

	* boot-9.scm: Load "ice-9/deprecated.scm" when appropriate.
	(try-load-module): Also try the old deprecated method, maybe.
	
2003-03-22  Marius Vollmer  <mvo@zagadka.de>

	* boot-9.scm (call/cc): Added.

2003-03-20  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* list.scm: New file.

2003-03-19  Marius Vollmer  <mvo@zagadka.de>

	* format.scm (format:out-substr): Update the column counter
	correctly. This fixes the behavior of ~T (tabbing) after ~F, for
	instance.  Thanks to Matthias Koeppe!

2003-03-13  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* session.scm (apropos): Don't look in duplicates interface.

2003-03-12  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* boot-9.scm (duplicate-handlers): Make sure the merge-generics
	and merge-accessors handlers are available also before (oop goops)
	has been loaded.  This is so that people can put them as default
	handlers without worrying about availability.

	* slib.scm (logical:ipow-by-squaring): Removed.

	* boot-9.scm (ipow-by-squaring): Removed.

	* boot-9.scm (beautify-user-module!): Don't install the duplicates
	handler here.

	default-module-duplicates-handler; Removed converter.
	(process-duplicates): Lookup default duplicates handler dynamically.
	(default-duplicate-binding-procedures): New parameter.

	* slib.scm (identity): Removed.  (Provided by core.)

2003-03-11  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* debugger/command-loop.scm: Prefix all commands imported from
	(ice-9 debugger command-loop) with debugger:.

	* boot-9.scm (process-duplicates): Use module-import-interface.

2003-03-04  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* session.scm (apropos): Use hash-for-each instead of
	array-for-each.

2003-02-19  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* boot-9.scm (make-module): Changed default size from 1021 to 31
	(since the size now adapts).
	(macro-table, xformer-table): Changed default size from 523 to 61.
	(make-module): Don't call make-hash-table with zero size.

	* Makefile.am (ice9_sources): Added weak-vector.scm.

	* weak-vector.scm: New file.

	* boot-9.scm (module-clear!): Use hash-clear!.

2003-02-11  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* boot-9.scm (make-hash-table): Turned primitive.

2003-01-27  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* syncase.scm (guile-macro): Strip syntactic information from
	expression before trying to treat it as a Guile macro call.
	(Thanks to Kevin Ryde.)

2003-01-24  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* threads.scm (parallel, letpar): Rewritten.

2003-01-23  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* threads.scm (par-mapper, n-par-map, n-par-for-each): Use
	futures.

2003-01-20  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* occam-channel.scm (alt): New syntax.

	* psyntax.ss (self-evaluating?): Removed.  Guile now provides this
	operator as a primitive procedure.
	(build-data): Quote vectors (psyntax.ss requires this).

2003-01-19  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* psyntax.ss (self-evaluating?): Allow procedures implanted in
	source.  (Guile uses this internally.)

2003-01-16  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* psyntax.ss (build-data): Don't quote self-evaluating expressions
	in output.  (We normally *would* like also these expressions to be
	quoted, but until Guile's native macros and syncase cooperates
	better, it is less destructive not to quote.)
	(self-evaluating?): Removed null? (In Guile, the empty list is not
	self-evaluating).
	(sc-chi): Export chi as sc-chi.
	(external-macro): New syntax type.

	* psyntax.pp: Regenerated.

	* compile-psyntax.scm: Set expansion-eval-closure.

	* boot-9.scm (use-syntax): Return *unspecified*.

	* syncase.scm: Set expansion-eval-closure to
	the-syncase-eval-closure during booting so that variables are
	created in the correct module.
	(syncase): Set expansion-eval-closure.
	(define-syntax define-syntax-public eval-when fluid-let-syntax
	identifier-syntax let-syntax letrec-syntax syntax syntax-case
	syntax-rules with-syntax include): Removed definitions (these are
	created from within psyntax.pp).
	Enable expansion of Guile macros during a syntax-case
	transformation.

2003-01-10  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* occam-channel.scm (make-channel): Renamed from channel.
	(make-timer): New function.

2002-12-04  Mikael Djurfeldt  <mdj@linnaeus>

	* threads.scm (parallel): New macro.
	 (par-map, par-for-each): New procedures.

	* documentation.scm (object-documentation): Added support for
	defmacros.

2002-11-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* boot-9.scm (re-export-syntax):  Re-introduced after accidentally
	removing it in my patch from 2002-11-16.

2002-11-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	Thanks to Mikael Djurfeldt for a bugreport which led to the
	following changes:

	* slib.scm (%system-define): Removed.

	(define): Changed to use define-private instead of
	%system-define.

	* boot-9.scm (define-private): Undid my changes from 2002-11-16
	until Guile supports hygienic macros.

2002-11-17  Neil Jerram  <neil@ossau.uklinux.net>

	* emacs.scm (emacs-load): Locally define `read-and-eval!', as it
	has been removed from the core.

2002-11-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* syncase.scm (define-syntax, eval-when, fluid-let-syntax,
	identifier-syntax, let-syntax, letrec-syntax, syntax, syntax-case,
	syntax-rules, with-syntax, include):  Changed definitions to form
	'real' macro definitions.

2002-11-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* boot-9.scm (define-private, export-syntax, export-syntax):
	Fixed my previous fix (blush).

2002-11-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* boot-9.scm (define-private, export-syntax, export-syntax):
	Changed definitions to form 'real' macro definitions.

2002-11-07  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* format.scm (format): Use 'monitor' properly.  Not the definition
	needs to be restricted, the actual function needs to be.

	* boot-9.scm (define-option-interface): Fix to "simplification"
	change below.

	arrangement didn't work if this module was loaded before (ice-9
	readline).)

2002-11-03  Marius Vollmer  <mvo@zagadka.ping.de>

	* format.scm (format): Wrap a monitor around format:format since
	it is not thread-safe.

2002-10-27  Marius Vollmer  <mvo@zagadka.ping.de>

	* threads.scm (%thread-handler): Explicitely return '#f'.  This
	value will be returned by join-thread.

	`guile-debugger' package ...

	should be unnecessary now.

2002-10-20  Mikael Djurfeldt  <mdj@linnaeus>

	* boot-9.scm (top-repl): Look for use-emacs-interface in
	guile-user-module (should it be there?) instead of

	* boot-9.scm (top-repl): Use 2 as the limit when saving the stack.
