2001-06-25  Marius Vollmer  <mvo@zagadka.ping.de>

	* srfi-8.scm: Use `re-export-syntax' to correctly re-export
	`receive'.

2001-06-18  Matthias Koeppe  <mkoeppe@mail.math.uni-magdeburg.de>

        The SRFI-19 implementation was completely broken.  Already the
	reference implementation did not handle DST and time zones
	properly and relied on non-R5RS-isms like passing reals to
	`quotient'.  For Guile, some additional fixes were needed because
	of the incomplete numeric tower implementation.  See also
	srfi-19.test. 
	
	* srfi-19.scm (date-zone-offset): Fixed typo in export clause.
	(add-duration): Renamed from priv:add-duration. 
	(priv:time-normalize!): Handle fractional nanoseconds; remove
	duplicate definition.
	(priv:current-time-tai): Fixed typo.
	(time=?, time<=?): Fixed typos.
	(time-tai->time-utc, time-utc->time-tai,
	time-utc->time-monotonic): Use make-time-unnormalized instead of
	make-time when uninitialized time fields are used.
	(set-date-nanosecond!, set-date-second!, set-date-minute!,
	set-date-hour!, set-date-day!, set-date-month!, set-date-year!,
	set-date-zone-offset!): Define.
	(priv:local-tz-offset): Take an extra argument in order to handle
	DST effects.
	(time-utc->date, time-tai->date, time-monotonic->date): Handle the
	changed signature of priv:local-tz-offset. Don't pass non-integer
	arguments to quotient (non-R5RS, not supported by Guile). 
	(date->time-utc): Ensure that seconds in a date structure are
	always exact integers.  Handle DST properly.
	(current-date, julian-day->date, modified-julian-day->date):
	Handle the changed signature of priv:local-tz-offset.  
	(julian-day->time-utc): Reverted earlier inexact->exact hack;
	make-time now handles inexact arguments.
	(priv:locale-print-time-zone): At least print the numerical time
	zone. 
	(priv:integer-reader): Fixed named let iteration.
	(priv:read-directives): Use set-date-month! instead of
	priv:set-date-month! etc.
	(string->date): Handle DST properly.

	SCM_UNUSED.

2001-06-07  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* srfi-1.scm (fold, fold-pair): Fixed a buggy call to apply.
	(delete-duplicates): Now the first occurrence of an element is
	retained, as required.
	(member, assoc): Fixed wrong order of equality predicate
	application.

2001-05-31  Michael Livshin  <mlivshin@bigfoot.com>

	* Makefile.am (MKDEP): copied from libguile/Makefile.am, just in
