	the functions below.

	* Makefile.am (noinst_HEADERS): Added conv-integer.i.c and

2004-07-29  Kevin Ryde  <user42@zip.com.au>

	* posix.c (scm_ttyname): Use scm_i_misc_mutex for thread safety.

2004-07-28  Kevin Ryde  <user42@zip.com.au>

	* posix.c (scm_ctermid): Use an L_ctermid buf on the stack, for thread
	safety.

	* unif.c (scm_array_set_x): For svect, use scm_num2short for
	consistency with other vector types and to get arg and func name into
	error message.

2004-07-27  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* deprecated.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP, SCM_BOOL):
	Reimplement using scm_is_false, scm_is_true, scm_is_bool, and
	scm_from_bool, respectively.
	(SCM_NINUMP): Added.
	
	* tags.h, deprecated.h (SCM_EQ_P): Deprecated by moving it into
	deprecated.h.  Replaced all uses with scm_is_eq.

2004-07-24  Kevin Ryde  <user42@zip.com.au>

	* threads.c, threads.h (scm_i_misc_mutex): New SCM_GLOBAL_MUTEX.
	* posix.c (scm_crypt): Use it to protect static data in crypt().

2004-07-23  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* deprecated.h, deprecated.c, numbers.h (SCM_INUMP, SCM_NINUMP,
	SCM_INUM): Deprecated by renaming them to SCM_I_INUMP,
	SCM_I_NINUMP and SCM_I_INUM, respectively and adding deprecated
	versions to deprecated.h and deprecated.c.  Changed all uses to
	either use the SCM_I_ variants or scm_is_*, scm_to_*, or
	scm_from_*, as appropriate.

	* dynwind.c (scm_i_dowinds): Removed unused code that would call
	the unexisting scm_cross_dynwind_binding_scope for inums on the
	windlist.
	
2004-07-10  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* 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
	an IPv& byte-wise address to a SCM integer.  Changed all uses.
	(bignum_in_ipv6_range_p, VALIDATE_INET6): Removed, their function
	is now done by scm_to_ipv6.
	
	* numbers.c (scm_to_signed_integer, scm_to_unsigned_integer): dot
	not accept inexact integers.

	* validate.h, deprecated.h (SCM_VALIDATE_INUM,
	SCM_VALIDATE_INUM_COPY, SCM_VALIDATE_BIGINT,
	SCM_VALIDATE_INUM_MIN, SCM_VALIDATE_INUM_MIN_COPY,
	SCM_VALIDATE_INUM_MIN_DEF_COPY,SCM_VALIDATE_INUM_DEF,
	SCM_VALIDATE_INUM_DEF_COPY, SCM_VALIDATE_INUM_RANGE,
	SCM_VALIDATE_INUM_RANGE_COPY): Deprecated because they make the
	fixnum/bignum distinction visible.  Changed all uses to
	scm_to_size_t or similar.

2004-07-09  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* cpp_cnvt.awk: Use scm_from_int instead of SCM_MAKINUM.

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

	* 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
	such a size causes divide-by-zeros in scm_hasher.

        * regex-posix.c (scm_make_regexp): Free rx on error, to avoid memory
	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_to_unsigned_integer, respectively, which is better(tm).  Also,
	use CHAR_BIT instead of hardcoding 8.
	(LLONG_MIN, LLONG_MAX, ULLONG_MAX): Removed and used
	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.c (SCM_I_LLONG_MIN, SCM_I_LLONG_MAX,
	SCM_I_ULLONG_MAX): Instead of hard-coding the numbers, compute
	them by assuming twos-complement.

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

	* 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.
	(scm_to_long_long, scm_to_ulong_long, scm_to_int8, scm_to_uint8,
	scm_to_int16, scm_to_uint16, scm_to_int32, scm_to_uint32,
	scm_to_int64, scm_to_uint64, scm_to_intmax, scm_to_uintmax,
	scm_from_long_long, scm_from_ulong_long, scm_from_int8,
	scm_from_uint8, scm_from_int16, scm_from_uint16, scm_from_int32,
	scm_from_uint32, scm_from_int64, scm_from_uint64, scm_from_intmax,
	scm_from_uintmax): New.
	
2004-07-06  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* tags.h (scm_is_eq): New.

	* 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_unsigned_integer, scm_to_schar, scm_to_uchar, scm_to_char,
	scm_to_short, scm_to_ushort, scm_to_long, scm_to_ulong,
	scm_to_size_t, scm_to_ssize_t, scm_from_schar, scm_from_uchar,
	scm_from_char, scm_from_short, scm_from_ushort, scm_from_int,
	scm_from_uint, scm_from_long, scm_from_ulong, scm_from_size_t,
	scm_from_ssize_t, scm_is_real, scm_to_double, scm_from_double):
	New.
	
2004-07-05  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* boolean.h, boolean.c (scm_is_true, scm_is_false, scm_from_bool,
	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
