	* socket.c (ipv6_net_to_num, scm_from_ipv6): Renamed
	ipv6_net_to_num to scm_from_ipv6, for converting from an IPv6
	byte-wise address to a SCM integer.  Changed all uses.
	(ipv6_num_to_net, scm_to_ipv6): Renamed ipv6_num_to_net to
	scm_to_ipv6 and added type and range checking, for converting from

	* hash.c (scm_hashq, scm_hashv, scm_hash): Restrict to size>=1 rather
	than size>=0, since 0<=hash<size cannot be satisfied for size==0, and

	leak.

2004-07-08  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* numbers.c (scm_is_signed_integer, scm_is_unsigned_integer):
	Rewritten using the same logic as scm_to_signed_integer and

	SCM_I_LLONG_MIN etc. instead.
	
	* numbers.h (SCM_MAKINUM, SCM_I_MAKINUM): Renamed SCM_MAKINUM to
	SCM_I_MAKINUM and changed all uses.
	* deprecated.h, deprecated.c (SCM_MAKINUM): Newly deprecated.

	* gen-scmconfig.h.in: Added all the new SCM_I_GSC_*_LIMITS that
	configure now produces.
	* gen-scmconfig.c: Use them to output SCM_T_INT8_MIN, etc
	definitions, giving the limits of the integer types defined by
	Guile. Also, output a hard coded SCM_I_LLONG_MIN, etc since
	LLONG_MIN or LONG_LONG_MIN is hard to get at.

	* numbers.h (scm_to_short, scm_to_ushort): It's SHRT_MIN, etc, not
	SHORT_MIN.
	(scm_to_size_t): Use SIZE_MAX instead of cooking our own.

	* deprecated.h, boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOL,
	SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into
	"deprecated.h".  Replaced all uses with scm_is_false, scm_is_true,
	scm_from_bool, and scm_is_bool, respectively.

	* boolean.h (scm_is_bool): Fix bug in prototype.
	(scm_from_bool): The argument is "x" not "f", stupid.

	* boolean.c (scm_is_bool): Fix typo.

	* numbers.h, numbers.c (scm_is_integer, scm_is_signed_integer,
	scm_is_unsigned_integer, scm_to_signed_integer,

	scm_to_bool): New.

2004-06-27  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* backtrace.c (display_expression, display_frame): Call
	scm_i_unmemoize_expr for unmemoizing a memoized object holding a
	single memoized expression.

	* debug.c (memoized_print): Don't try to unmemoize the memoized
	object, since we can't know whether it holds a single expression
	or a body.

	(scm_mem_to_proc): Removed check for lambda expression, since it
	was moot anyway.  Whoever uses these functions for debugging
	purposes should know what they do: Creating invalid memoized code
	will cause crashes, independent of whether this check is present
	or not.

	(scm_proc_to_mem): Take the closure's code as it is and don't
	append a SCM_IM_LAMBDA isym.  To allow easier debugging, the
	memoized code should not be modified.

	* debug.[ch] (scm_unmemoize, scm_i_unmemoize_expr): Removed
	scm_unmemoize from public use, but made scm_i_unmemoize_expr
	available as a guile internal function instead.  However,
	scm_i_unmemoize_expr will only work on memoized objects that hold
	a single memoized expression.  It won't work with bodies.

	* debug.c (scm_procedure_source), macros.c (macro_print), print.c
	(scm_iprin1): Call scm_i_unmemocopy_body for unmemoizing a body,
	i. e. a list of expressions.

	* eval.c (unmemoize_exprs): Drop internal body markers from the
	output during unmemoization.

	* eval.[ch] (scm_unmemocopy, scm_i_unmemocopy_expr,
	scm_i_unmemocopy_body): Removed scm_unmemocopy from public use,
	but made scm_i_unmemocopy_expr and scm_i_unmemocopy_body available
	as guile internal functions instead.  scm_i_unmemoize_expr will
	only work on a single memoized expression, while
	scm_i_unmemocopy_body will only work on bodies.

2004-06-21  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* eval.c (unmemoize_exprs): Handle semi-memoized code.

	(scm_cons_source, scm_primitive_eval): Prefer higher level
	predicate SCM_FALSEP over SCM_IMP.

2004-06-15  Rob Browning  <rlb@defaultvalue.org>

	* script.c (scm_shell_usage): minor phrasing change.

	* gc_os_dep.c: update ifdefery for macosx.
	(scm_get_stack_base): separate result initialization from
	declaration to slience warnings with macosx and hp-ux using gcc

	11	advantage of this.
	12	* fports.c (scm_open_file): Use scm_strerror likewise.
	13	* filesys.c (scm_stat, scm_lstat): Ditto.
	14
	15	* filesys.c (scm_copy_file): Avoid fd leak when destination file
	16	cannot be opened.
	17

	19	update, for thread safety.

	150	* numbers.c (scm_is_signed_integer, scm_is_unsigned_integer):
	151	Rewritten using the same logic as scm_to_signed_integer and
	152	scm_to_unsigned_integer, respectively, which is better(tm). Also,
	153	use CHAR_BIT instead of hardcoding 8.
	154	(LLONG_MIN, LLONG_MAX, ULLONG_MAX): Removed and used
	155	SCM_I_LLONG_MIN etc. instead.
	156
	157	* numbers.h (SCM_MAKINUM, SCM_I_MAKINUM): Renamed SCM_MAKINUM to
	158	SCM_I_MAKINUM and changed all uses.
	159	* deprecated.h, deprecated.c (SCM_MAKINUM): Newly deprecated.
	160
a3de8e7b MV	161	* gen-scmconfig.c (SCM_I_LLONG_MIN, SCM_I_LLONG_MAX,
a3de8e7b MV	162	SCM_I_ULLONG_MAX): Instead of hard-coding the numbers, compute
43240c9c MV	163	them by assuming twos-complement.

	166
	167	* gen-scmconfig.h.in: Added all the new SCM_I_GSC_*_LIMITS that
	168	configure now produces.
	169	* gen-scmconfig.c: Use them to output SCM_T_INT8_MIN, etc
	170	definitions, giving the limits of the integer types defined by
	171	Guile. Also, output a hard coded SCM_I_LLONG_MIN, etc since
	172	LLONG_MIN or LONG_LONG_MIN is hard to get at.
	173
	174	* numbers.h (scm_to_short, scm_to_ushort): It's SHRT_MIN, etc, not
	175	SHORT_MIN.
	176	(scm_to_size_t): Use SIZE_MAX instead of cooking our own.
	177	(scm_to_long_long, scm_to_ulong_long, scm_to_int8, scm_to_uint8,
	178	scm_to_int16, scm_to_uint16, scm_to_int32, scm_to_uint32,
	179	scm_to_int64, scm_to_uint64, scm_to_intmax, scm_to_uintmax,
	180	scm_from_long_long, scm_from_ulong_long, scm_from_int8,
	181	scm_from_uint8, scm_from_int16, scm_from_uint16, scm_from_int32,
	182	scm_from_uint32, scm_from_int64, scm_from_uint64, scm_from_intmax,
	183	scm_from_uintmax): New.
	184

	186
	187	* tags.h (scm_is_eq): New.
	188
	189	* deprecated.h, boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOL,
	190	SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into
	191	"deprecated.h". Replaced all uses with scm_is_false, scm_is_true,
	192	scm_from_bool, and scm_is_bool, respectively.
	193
	194	* boolean.h (scm_is_bool): Fix bug in prototype.
	195	(scm_from_bool): The argument is "x" not "f", stupid.
	196
	197	* boolean.c (scm_is_bool): Fix typo.
	198
	199	* numbers.h, numbers.c (scm_is_integer, scm_is_signed_integer,
	200	scm_is_unsigned_integer, scm_to_signed_integer,
	201	scm_to_unsigned_integer, scm_to_schar, scm_to_uchar, scm_to_char,
	202	scm_to_short, scm_to_ushort, scm_to_long, scm_to_ulong,
	203	scm_to_size_t, scm_to_ssize_t, scm_from_schar, scm_from_uchar,
	204	scm_from_char, scm_from_short, scm_from_ushort, scm_from_int,
	205	scm_from_uint, scm_from_long, scm_from_ulong, scm_from_size_t,
	206	scm_from_ssize_t, scm_is_real, scm_to_double, scm_from_double):
	207	New.

800570a6 MV	209	2004-07-05 Marius Vollmer <marius.vollmer@uni-dortmund.de>
	210
	211	* boolean.h, boolean.c (scm_is_true, scm_is_false, scm_from_bool,
	212	scm_to_bool): New.
	213
9fcf3cbb DH	214	2004-06-27 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
	215
	216	* backtrace.c (display_expression, display_frame): Call
	217	scm_i_unmemoize_expr for unmemoizing a memoized object holding a
	218	single memoized expression.
	219
	220	* debug.c (memoized_print): Don't try to unmemoize the memoized
	221	object, since we can't know whether it holds a single expression
	222	or a body.
	223
	224	(scm_mem_to_proc): Removed check for lambda expression, since it
	225	was moot anyway. Whoever uses these functions for debugging
	226	purposes should know what they do: Creating invalid memoized code
	227	will cause crashes, independent of whether this check is present
	228	or not.
	229
	230	(scm_proc_to_mem): Take the closure's code as it is and don't
	231	append a SCM_IM_LAMBDA isym. To allow easier debugging, the
	232	memoized code should not be modified.
	233
	234	* debug.[ch] (scm_unmemoize, scm_i_unmemoize_expr): Removed
	235	scm_unmemoize from public use, but made scm_i_unmemoize_expr
	236	available as a guile internal function instead. However,
	237	scm_i_unmemoize_expr will only work on memoized objects that hold
	238	a single memoized expression. It won't work with bodies.
	239
	240	* debug.c (scm_procedure_source), macros.c (macro_print), print.c
	241	(scm_iprin1): Call scm_i_unmemocopy_body for unmemoizing a body,
	242	i. e. a list of expressions.
	243
	244	* eval.c (unmemoize_exprs): Drop internal body markers from the
	245	output during unmemoization.
	246
	247	* eval.[ch] (scm_unmemocopy, scm_i_unmemocopy_expr,
	248	scm_i_unmemocopy_body): Removed scm_unmemocopy from public use,
	249	but made scm_i_unmemocopy_expr and scm_i_unmemocopy_body available
	250	as guile internal functions instead. scm_i_unmemoize_expr will
	251	only work on a single memoized expression, while
	252	scm_i_unmemocopy_body will only work on bodies.
	253
90df793f DH	254	2004-06-21 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
	255
	256	* eval.c (unmemoize_exprs): Handle semi-memoized code.
	257
	258	(scm_cons_source, scm_primitive_eval): Prefer higher level
	259	predicate SCM_FALSEP over SCM_IMP.
	260
8048c00b RB	261	2004-06-15 Rob Browning <rlb@defaultvalue.org>
	262
	263	* script.c (scm_shell_usage): minor phrasing change.
	264
	265	* gc_os_dep.c: update ifdefery for macosx.
	266	(scm_get_stack_base): separate result initialization from
	267	declaration to slience warnings with macosx and hp-ux using gcc
	268
