2001-04-01  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        * gc.c (MARK):  Re-introduce a cheap sanity test for non debug
        mode, as suggested by Michael Livshin.

2001-03-31  Michael Livshin  <mlivshin@bigfoot.com>

        * backtrace.c (display_backtrace_body): since the `print_state'
        variable is not used (instead its data field is used directly as
        `pstate'), protect it from the hungry compiler optimizations.
        thanks to Bill Schottstaedt for the report.

2001-03-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        * gc.[ch] (scm_tc16_allocated):  New type tag for allocated cells.
        It is only defined and used if guile is compiled with
        SCM_DEBUG_CELL_ACCESSES set to true.  It's purpose is, to never
        let cells with a free_cell type tag be visible outside of the
        garbage collector when in debug mode.

        * gc.c (scm_debug_cell_accesses_p):  Set to true as default.

        (scm_assert_cell_valid):  Use a local static variable to avoid
        recursion.

        (MARK):  Only check for rogue cell pointers in debug mode.  Use
        scm_cellp for this purpose and place all checks for rogue pointers
        into that function.  Further, since due to conservative scanning
        we may encounter free cells during marking, don't use the standard
        cell type accessor macro to determine the cell type.

        (scm_cellp):  Check if the cell pointer actually points into a
        card header.

        (scm_init_gc):  Initalize scm_tc16_allocated.

        * gc.h (GCH):  Renamed to SCM_GC_H.

        (SCM_VALIDATE_CELL):  Enclose the expression in brackets.  This
        might be unnecessary, but I feel better this way :-)

        (SCM_GC_CELL_TYPE):  New macro.

        (SCM_SETAND_CDR, SCM_SETOR_CDR):  Deprecated.  These are not used
        in guile, and it is unlikely that they will be applied to real
        pairs anyway.

        (SCM_SET_FREE_CELL_TYPE):  Removed.  It was not used.

        (SCM_GC_SET_ALLOCATED):  New macro.  Only non-empty if guile is
        compiled with SCM_DEBUG_CELL_ACCESSES set to true.

        (SCM_NEWCELL, SCM_NEWCELL2):  Use of SCM_GC_SET_ALLOCATED will
        make sure that in debug mode no free cell will ever be visible
        outside of the garbage collector.

2001-03-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        * async.c (scm_asyncs_pending):  Don't use != to compare SCM
        values.

        * async.c (scm_system_async), variable.c (scm_make_variable,
        scm_make_undefined_variable):  Use scm_cons to create a pair.

        * debug.c (scm_reverse_lookup):  Perform proper type checking.
        Remove suspicious use of SCM_SLOPPY_CONSP.

        * eq.c (scm_equal_p), tags.h (SCM_ECONSP):  Use SCM_CONSP instead
        of SCM_SLOPPY_CONSP.  A sane compiler should be able to perform
        the corresponding optimization.

        * eval.c (iqq):  Use proper type check.

        (scm_m_expand_body):  Remove redundant type checks.

        (promise_print):  Don't access promise cells as pairs.

        * eval.c (EVALCAR, iqq, scm_m_expand_body, scm_eval_args,
        scm_deval_args SCM_CEVAL), guardians.c (scm_guard), hashtab.c
        (scm_internal_hash_fold), print.c (scm_iprlist):  Use !SCM_CELLP
        for SCM_NCELLP, !SCM_CONSP for SCM_NCONSP, !SCM_IMP for SCM_NIMP,
        !SCM_FALSEP for SCM_NFALSEP, !SCM_NULLP for SCM_NNULLP

        * eval.c (scm_m_define, scm_macroexp, SCM_CEVAL), print.c
        (scm_iprin1):  Use new macro predicate and accessors.

        * eval.h (scm_tc16_macro):  Removed declaration.  It is declared
        in macros.h.

        * eval.h (EVALH), macros.h (MACROSH), ports.h (PORTSH), procs.h
        (PROCSH), tags.h (TAGSH), variable.h (VARIABLEH):  Renamed to
        SCM_EVAL_H, SCM_MACROS_H, SCM_PORTS_H, SCM_PROCS_H, SCM_TAGS_H and
        SCM_VARIABLE_H.  Even the macros that are used to inhibit
        including a header file twice should be in the SCM_ namespace.

        * fluids.c (scm_swap_fluids, scm_swap_fluids_reverse),
        properties.c (scm_primitive_property_ref,
        scm_primitive_property_del_x):  Prefer stronger predicates like
        SCM_NULLP or SCM_FALSEP over SCM_IMP.

        * gc.c (MARK):  Use proper macros to access procedure-with-setter
        cell elements and closure cell elements.

        (gc_sweep_freelist_finish, scm_gc_sweep, init_heap_seg):  Don't
        access free cells as pairs.

        (scm_unprotect_object):  scm_hashq_get_handle returns #f if
        no hashtab entry is found.

        * gc.c (scm_gc_sweep), ports.c (scm_close_port):  Use new macro
        SCM_CLR_PORT_OPEN_FLAG.

        * guardians.c (TCONC_IN), print.c (scm_free_print_state):  Don't
        use SCM_SET_C[AD]R for uninitialized cells.

        * hashtab.c (scm_hash_fn_get_handle):  Use SCM_VALIDATE_VECTOR.
        If the hashtable has no slots, return #f instead of '().  This
        unifies the return value with most assoc-functions.

        (scm_hash_fn_ref):  Use proper type check.

        (scm_hashq_get_handle, scm_hashv_get_handle, scm_hash_get_handle):
        Removed references to non-existing functions from documentation.

        * keywords.c (scm_keyword_dash_symbol):  Use proper macros to
        access keyword cell elements.

        * macros.h (SCM_MACROP, SCM_MACRO_TYPE, SCM_MACRO_CODE):  New
        macros.

        * ports.h (SCM_CLR_PORT_OPEN_FLAG):  New macro.

        * print.c (scm_iprlist):  Added comment.  Improved loop
        conditions.

        * procs.h (SCM_ENV, SCM_SETENV):  Don't access closure cells as
        pairs.

        * smob.c (scm_markcdr):  Don't access smob cells as pairs.

        * tags.h (SCM_SLOPPY_CONSP, SCM_SLOPPY_NCONSP):  Deprecated.

        * throw.c (ACTIVATEJB, DEACTIVATEJB):  Don't access jump buffer
        cells as pairs.

        * variable.c (variable_print, variable_equalp, scm_variable_ref,
        scm_variable_set_x):  Use proper macros to access variable cell
        elements.

        (scm_variable_bound_p):  Don't use SCM_NEGATE_BOOL.

        * variable.h (SCM_VARVCELL):  Don't access variable cells as
        pairs.

        * vectors.c (scm_vector), weaks.c (scm_weak_vector):  Simplified,
        added FIXME comment, removed register specifier.

2001-03-29  Keisuke Nishida  <kxn30@po.cwru.edu>

        * goops.c, goops.h (scm_init_oop_goops_goopscore_module): Deprecated.
        * init.c (scm_init_guile_1): Don't init goopscore module.

2001-03-27  Marius Vollmer  <mvo@zagadka.ping.de>

        * values.h (scm_values_vtable, SCM_VALUESP): Moved here so that
        eval.c can use it.
        (scm_call_with_values): Removed.
        * values.c (values_vtable, scm_values_vtable): Added "scm_" prefix
        so that it can be exported.
        (scm_call_with_values): Removed.
        
        * tags.h (SCM_IM_CALL_WITH_VALUES): New isym.

        SCM_ASSYNT.

2001-03-15  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        * gh.h/gh_data.c (gh_ints2scm):  Changed the signature to use a
        const int* to reflect that the input array of integers remains
        unchanged.  Thanks to Brett Viren for the hint.

2001-03-14  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

        * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs),
        (gh_scm2floats, gh_scm2doubles): Check for malloc() returning NULL
        in various places.
        (gh_scm2newstr, gh_symbol2newstr): Change call to
        scm_must_malloc() to malloc(), because user-free()able memory is
        allocated.

        * gc.c: Added declaration of `scm_debug_check_freelist'.

2001-03-13  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

        * goops.c (scm_m_atslot_ref, scm_m_atslot_set_x,
        scm_m_atdispatch):  Provide definitions for FUNC_NAME.  Don't use
        SCM_ASSYNT to check for correct argument types.  Either use some
        SCM_VALIDATE_* macro or an explicit test.

        (scm_make_foreign_object):  Don't use SCM_ASSERT to check for
        misc-errors.

        * macros.h (SCM_ASSYNT):  On assertion failure, issue a misc-error
        instead of calling scm_wta.

        * load.c (scm_primitive_load, scm_primitive_load_path),
        (scm_sys_search_load_path): Corrected docstrings (file ->
        filename).

        * eval.c (scm_force): Added texinfo markup to docstring.

        * debug-malloc.c: Reinserted #include <stdio.h>.

2001-03-11  Keisuke Nishida  <kxn30@po.cwru.edu>

        * list.c (s_scm_reverse_x): Use SCM_VALIDATE_LIST.

        * environments.c, error.c, eval.c, filesys.c, hashtab.c, load.c,
        net_db.c, procprop.c, read.c, scmsigs.c, socket.c, struct.c:
        Use SCM_LISTn instead of scm_listify.

2001-03-10  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

        * _scm.h: Removed #include <errno.h>.

        * error.c, net_db.c, putenv.c, stime.c: Removed declaration of
        errno variable (can be a macro on some systems, for example when
        using linux libc with threads).

        * error.c, filesys.c, gc.c, ioext.c, iselect.c, net_db.c, ports.c,
        posix.c, print.c, putenv.c, scmsigs.c, script.c, simpos.c, smob.c,
        socket.c, srcprop.c, stime.c, strop.c, unif.c, vports.c: Added
        #include <errno.h> in these 20 out of 100 files.
        
2001-03-10  Gary Houston  <ghouston@arglist.com>

        * socket.c: add a definition of SUN_LEN (from glibc) for when it's
        not already defined.

2001-03-09  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

        * coop.c: Inserted #include <stdio.h>.

        * iselect.c: Reinserted #include <stdio.h>.

2001-03-10  Marius Vollmer  <mvo@zagadka.ping.de>

        * posix.c: Replaced `#define' of __USE_XOPEN right before
        including unistd.h with a define of _GNU_SOURCE at the very top of
        the file.

        (scm_sethostname, scm_gethostname): New prototypes.

        * posix.c: Added inclusion of <crypt.h>, <sys/resource.h> and
        <sys/file.h>, if present.

        LOCK_EX, LOCK_UN, LOCK_NB]: New variables.
        (scm_crypt, scm_chroot, scm_getlogin, scm_cuserid),
        (scm_getpriority, scm_setpriority, scm_getpass, scm_flock),
        (scm_sethostname, scm_gethostname): New procedures.

2001-03-08  Neil Jerram  <neil@ossau.uklinux.net>

        * ports.c (scm_port_column): Docstring fixes: (i) port-line arg is
        not optional (ii) "recommend" spelling correction.

2001-03-08  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

        * ramap.c (racp): Removed optimization which caused array copying
        to fail if the two arrays shared storage.  Re-inserted the IVDEP
        macros removed in the change of 2000-03-09.  (Don't really have a
        complete grasp of what they are for, but they seem to be necessary
        on Crays.  This needs testing!)  Thanks to Miroslav Silovic.

        * hash.c (scm_string_hash): Don't downcase characters.

2001-03-07  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

        * symbols.c (scm_symbols_prehistory): Changed symbol hash table

        function.

        * coop-threads.c: Fixed change of 2001-03-06.
        
        * validate.h: Code formatting.

2001-03-07  Keisuke Nishida  <kxn30@po.cwru.edu>

        * Makefile.am (*.x): Add dependency on snarf.h and guile-doc-snarf.in.
        (*.doc): Add dependency on guile-snarf.awk.in.

        * guile-snarf.awk.in: Neglect spaces at the end of
        SCM_SNARF_DOCSTRING_END.  Skip lines "# NN ..." in the
        middle of docstrings.  (To avoid the problem with gcc-2.96.)

2001-03-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        * coop-threads.c (scm_call_with_new_thread), load.c
        (scm_primitive_load, scm_sys_search_load_path), random.c
        (scm_c_default_rstate), struct.c (scm_make_struct_layout,
        scm_struct_ref, scm_struct_set_x):  Don't use SCM_ASSERT to
        (potentially) issue a scm-misc-error or wrong-num-args error
        message.

        * load.c (scm_search_path):  Use SCM_ASSERT_TYPE to give details
        about the expected type with the wrong-type-arg error message.

        * smob.c (scm_make_smob):  Abort on misuse of smob - it indicates
        a C level bug that can't be fixed from scheme anyway.

2001-03-05  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

        * eval.c (scm_m_letstar): Removed check for duplicate bindings.
        Duplicate bindings are OK in a let* since a let* is semantically
        equivalent to a nested set of let:s.

2001-03-05  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

        * print.c (scm_print_options): Fixed texinfo in docstring.

        * net_db.c (scm_getserv, scm_getproto, scm_getnet): Return #f if
        the underlying functions getservent, getprotoent or getnetent
        return NULL instead of signalling an error.

2001-03-04  Gary Houston  <ghouston@arglist.com>

        * socket.c (scm_fill_sockaddr): don't allow buffer overflows when
        taking an unexpectedly large filename for an AF_UNIX socket from
        bind/connect/sendto (thanks to Martin Grabmueller).
        
        * socket.c (scm_sock_fd_to_port, SCM_SOCK_FD_TO_PORT): removed the
        former and adjusted the latter.
        (scm_socket, scm_socketpair): cosmetic changes.
        (scm_getsockopt, scm_setsockopt): declare optlen as int, not
        size_t as socklen_t substitute.  don't restrict args/return values
        to INUM: allow full range of int or size_t.
        (scm_fill_sockaddr): check arguments before allocating memory, to
        avoid leakage.  use malloc, not scm_must_malloc.
        (scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
        substitute.  free the sockaddr structure before throwing an error.
        (scm_init_add_buffer): procedure removed, together with its static
        buffer scm_addr_buffer, which wouldn't be thread safe.  instead,
        define a macro MAX_ADDR_SIZE and declare the buffer where needed.
        (scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
        scm_sendto): use a local buffer instead of scm_addr_buffer.
        adjust for new SCM_SOCK_FD_TO_PORT.  use int for address size,
        not size_t.
        (scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
        call to detect whether recvfrom could be bothered to set the address.
        (scm_init_socket): don't call scm_init_addr_buffer.

        (SCM_VALIDATE_NUMBER_COPY):  Don't call function scm_wta, call
        scm_misc_error or scm_wrong_type_arg instead.

        * validate.h (SCM_WTA, RETURN_SCM_WTA):  Deprecated.

2001-03-04  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

        * goops.c, goops.h (scm_sys_pre_expand_closure_x): Removed.

        call function scm_wta, call scm_misc_error or scm_wrong_type_arg
        instead.

2001-03-04  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

        * goops.c (scm_sys_pre_expand_closure_x): New procedure.

2001-03-04  Marius Vollmer  <mvo@zagadka.ping.de>

        * eval.c (scm_s_duplicate_formals): New error message string.
        (scm_c_improper_memq): New function.
        (scm_m_lambda): Check for duplicate arguments.
        (scm_ceval, scm_deval): When executing a body: only cons a new
        toplevel environment frame when it is different from the
        existing one; use EVALCAR instead of SIDEVAL so that we can properly
        check for empty combinations; use SCM_EVALIM2 for the same reason
        in the non-toplevel loop.
        (nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
        New labels with the meaning of their non-"nontoplevel" partners,
        but they are used when it is known that the body is not evaluated at
        top-level.
        (scm_apply, scm_dapply): use SCM_EVALIM2 to get proper error
        reporting for empty combinations.

        (scm_string_ci_geq_p), symbols.c (scm_symbol_p)
        (scm_symbol_to_string, scm_string_to_symbol): Changed use of @t{}

        * struct.c (scm_struct_p, scm_struct_vtable_p): Added texinfo

2001-02-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        (Obviously nobody compiles with SCM_RECKLESS defined...)

        * validate.h (SCM_ASSERT_RANGE):  Use the argument number.

2001-02-23  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

        scm_make_polar): Rename arguments `z1' and `z2' to `x' and `y',

        typos.

2001-02-23  Neil Jerram  <neil@ossau.uklinux.net>

        * goops.c (scm_add_method, DEFVAR): Use scm_eval instead of
        scm_i_eval.
        (make_class_from_template): Do not bother to set the current
        module around the call to DEFVAR, scm_eval takes care of that.
        (scm_init_goops): Make scm_module_goops and
        scm_goops_lookup_closure permanent objects.
        
        * eval.c (scm_ceval, scm_deval): When evaluating expressions on
        top level, create a fresh top-level environment for each
        expression instead of mutating the exisint frame.  This is
        important when that frame is closed over.

        * numbers.c (s_scm_logior) [SCM_DIGSTOOBIG]: Also use
        SCM_DIGSPERLONG instead of DIGSPERLONG.

2001-02-21  Marius Vollmer  <mvo@zagadka.ping.de>

        * eval.c (scm_ceval, scm_deval): Check for wrong number of args

        evaluated at top-level and synronize lookup closure before
        executing every subform.
        (scm_primitve_eval_x, scm_primitive_eval): New functions.

        * modules.h (scm_selected_module, scm_current_module): Renamed
        scm_selected_module to scm_current_module to synchronize Scheme
        and C names.
        (scm_select_module, scm_set_current_module): Likewise.  Changed
        all uses.
        
        * ports.c (scm_port_for_each): Make a snapshot of the port table
        before iterating over it.  The table might change while the user
        code is running.  With the snapshot, the user can depend on the
        fact that each port that existed at the start of the iteration is
        encountered exactly once.  (ice-9 popen) depends on this.

        checking of the size parameter for type correctness and valid
        range.  Thanks to Rob Browning for reporting the problem.  Instead
        of deferring interrupts, scm_remember_upto_here_1 is used.

        * strop.c (string_copy, string_upcase_x, string_downcase_x,
        string_capitalize_x):  New functions.  Each one performs the core

        read from had an associated filename.  Thanks to Martin
        Grabmueller for providing this patch.

        This patch was sent by Martin Grabmueller and makes sure that
        parameter errors are reported correctly by the lexicographic
        ordering predicates.

        * strorder.c (string_less_p, string_ci_less_p):  New functions.

        (scm_string_less_p, scm_string_ci_less_p):  Extracted the core
        functionality into string_less_p, string_ci_less_p respectively.
        The remaining code is just a wrapper to do the parameter
        checking.

        (scm_string_leq_p, scm_string_gr_p, scm_string_geq_p):  Check the
        parameters and call string_less_p instead of scm_string_less_p.

        (scm_string_ci_leq_p, scm_string_ci_gr_p, scm_string_ci_geq_p):
        Check the parameters and call string_less_ci_p instead of
        scm_string_ci_less_p.

2001-01-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        This patch modifies scm_display_error to perform parameter
        checking.  Thanks to Neil Jerram for the bug report.

        * backtrace.[ch] (scm_i_display_error):  New function.

        * backtrace.c (scm_display_error):  Added parameter check and
        extracted the core functionality into function
        scm_i_display_error.

        * throw.c (handler_message):  Call scm_i_display_error to display
        the error message.

2001-01-23  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

        * eval.c (SCM_APPLY): Added # args check for application of

        Instead, give an explicit error message in case the directory is
        closed.

        (scm_closedir, scm_dir_print):  Rewritten to use SCM_DIR_OPEN_P
        instead of SCM_OPENP and SCM_CLOSEDP.

2001-01-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        * eval.c (inner_eval, scm_eval):  Move all real functionality into
        inner_eval.  Avoid to copy the expression twice by inlining some
        code from scm_i_eval.

2001-01-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        * eval.c (scm_m_case):  The 'else' clause of a 'case' statement
        now has to be the last clause, as required by R5RS.  Thanks to
        Martin Grabmueller for the patch.

2001-01-18  Gary Houston  <ghouston@arglist.com>

        * ioext.c: further simplify scm_read_string_x_partial by defining

2001-01-17  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        * __scm.h (SCM_FIXNUM_BIT):  Added.  The name is chosen in analogy
        to the names in limits.h.

        * numbers.c (abs_most_negative_fixnum):  Added.

        (scm_quotient, scm_remainder):  Fixed the fixnum-min / (abs
        fixnum-min) special case.

        (scm_big_and):  Fix for negative first parameter.

        (scm_bit_extract):  Fix for fixnum paramters.
        Thanks to Rob Browning for the bug report.

        Thanks to Bill Schottstaedt.

2001-01-11  Michael Livshin  <mlivshin@bigfoot.com>

        from Matthias Köppe:
        
        * objects.h (SCM_SET_ENTITY_SETTER): new macro.  SCM_ENTITY_SETTER
        casts its result, so doesn't yield an lvalue per ANSI C.

        * goops.c (s_scm_sys_set_object_setter_x): use
        SCM_SET_ENTITY_SETTER.
        (clear_method_cache): use SCM_SET_ENTITY_PROCEDURE.

        * gc.h (SCM_GC_SET_CARD_BVEC): new macro.  SCM_GC_CARD_BVEC casts
        its result, so doesn't yield an lvalue per ANSI C.
        (SCM_GC_SET_CARD_FLAGS): ditto for SCM_GC_GET_CARD_FLAGS.
        (SCM_GC_CLR_CARD_FLAGS): redefined in terms of
        SCM_GC_SET_CARD_FLAGS.
        (SCM_GC_SET_CARD_FLAG, SCM_GC_CLR_CARD_FLAGS): ditto.

        * gc.c (INIT_CARD): use the explicit setter macro to set the bvec.

2001-01-08  Gary Houston  <ghouston@arglist.com>

        * validate.h (SCM_VALIDATE_SUBSTRING_SPEC_COPY): new macro.
        * ioext.c (scm_read_string_x_partial, scm_read_delimited_x),
        socket.c (scm_recvfrom): use the new macro, plus minor docstring
        changes.
        * ioext.c (scm_read_string_x_partial): don't crash if -1 is supplied
        for fdes.  if current input port is used, check that it's a file
        port.

2001-01-06  Gary Houston  <ghouston@arglist.com>

        * ioext.c (scm_read_string_x_partial): new procedure, implements
        read-string!/partial.
        * ports.c (scm_take_from_input_buffers): new procedure used by
        scm_read_string_x_partial.
        (scm_drain_input): use scm_take_from_input_buffers.

2001-01-06  Marius Vollmer  <mvo@zagadka.ping.de>

        * validate.h (SCM_VALIDATE_NUMBER): New.

2001-01-03  Michael Livshin  <mlivshin@bigfoot.com>

        * guardians.c (F_GREEDY, F_LISTED, F_DESTROYED, GREEDY_P,
        SET_GREEDY, LISTED_P, SET_LISTED, CLR_LISTED, DESTROYED_P,
        SET_DESTROYED): new defines/macros.
        (GUARDIAN_LIVE, GUARDIAN_ZOMBIES, GUARDIAN_NEXT): deleted.
        (add_to_live_list): takes a `guardian_t *' now, not SCM.
        (guardian_print): print more info.
        (guardian_apply): check if the guardian is destroyed, and throw an
        error if so.  take one more optional argument `throw_p'.
        (scm_guard): depending on the value of `throw_p', return a boolean
        result.
        (scm_get_one_zombie): remove redundant property test.
        (guardian_t): represent the various (currently 3, I hope nothing
        more gets added) boolean fields as bit flags.
        (scm_guardian_destroyed_p, scm_guardian_greedy_p): new predicates.
        (scm_destroy_guardian_x): new procedure.

        * guardians.h: added prototypes for `scm_guardian_greedy_p' and
        `scm_guardian_destroyed_p'.  changed prototype for `scm_guard'.

2001-01-01  Gary Houston  <ghouston@arglist.com>

        * fports.c (fport_write): bugfix: handle short writes for
        unbuffered ports too.  optimize the buffered case by minimizing
        the number of write/flush calls.
        (write_all): new helper procedure.
