2004-06-13  Han-Wen Nienhuys   <hanwen@xs4all.nl>

	* eval.c (unmemoize_exprs): use SCM_CONSP for the loop condition.

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

	* list.[ch] (scm_i_finite_list_copy): New internal function to
	copy lists that are known to be finite (though not necessarily
	proper).

	* debug.c (scm_procedure_source): Don't have scm_unmemocopy treat
	a closure's argument list like an expression of a body.

	* eval.c (unmemoize_expression, unmemoize_exprs, unmemoize_and,
	unmemoize_begin, unmemoize_case, unmemoize_cond, unmemoize_delay,
	unmemoize_do, unmemoize_if, unmemoize_lambda, unmemoize_let,
	unmemoize_letrec, unmemoize_letstar, unmemoize_or,
	unmemoize_set_x, unmemoize_apply, unmemoize_atcall_cc,
	unmemoize_at_call_with_values, unmemoize_future, sym_atslot_ref, 
	unmemoize_atslot_ref, sym_atslot_set_x, unmemoize_atslot_set_x,
	unmemoize_builtin_macro): New static functions and symbols.

	(scm_unmemocopy): Rewritten in terms of the above.  scm_unmemocopy
	now has a slightly different meaning: The memoized form that is
	receives as its argument is now interpreted as a sequence of
	expressions from a body.

	(unmemocar, scm_unmemocar): Since the whole functionality of
	unmemocar and scm_unmemocar is not needed any more, scm_unmemocar
	has its old content back and is deprecated, while unmemocar has
	been removed.

	(SCM_BIT7): Removed.

	(CEVAL): For unmemoizing a single expression, call
	unmemoize_expression instead of scm_unmemocopy, which now expects
	a sequence of body expressions.  Eliminated unnecessary empty
	environment frame when executing let* forms.  Eliminated
	unmemoization step from evaluator.

2004-06-02  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* eval.c (scm_macroexp, macroexp): Renamed scm_macroexp to
	macroexp and made static.  Added new version of scm_macroexp that
	emits a deprecation warning and then calls macroexp.
	(scm_m_undefine): Issue deprecation warning.
	
2004-05-30  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* eval.c (lookup_global_symbol, literal_p, try_macro_lookup):
	Modified to make set! work on symbols that represent syntactic
	keywords.

2004-05-26  Han-Wen Nienhuys   <hanwen@xs4all.nl>

	* gc.h (SCM_CELL_OBJECT_LOC): use SCM_GC_CELL_OBJECT to prevent
	compound expression as lvalue errors.

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

	* dynwind.c (winder_mark): Use SCM_PACK to correctly convert the
	WINDER_DATA to a SCM.

2004-05-24  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* goops.c (compute_getters_n_setters, create_standard_classes,
	scm_add_slot): Compute closures by calling scm_i_eval_x on a
	lambda expression rather than creating them with scm_closure.

2004-05-22  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* eval.c (s_macro_keyword, scm_m_set_x): Remove checking for
	misplaced syntactic keywords.  This will not work unless guile's
	defmacro feature is deprecated.

	(scm_m_case): Fixed a bug that caused the list of labels to grow
	with every case form.

2004-05-19  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_round_number): For inum and big, just return x.  For
	real, use scm_round for 2^54-1 etc problems covered there.

	* numbers.c (trunc): Remove #define to scm_truncate when the C library
	doesn't provide trunc.  This was for when `truncate' was done as a
	scm_tc7_dsubr, no longer required.

	* threads.c (scm_threads_mark_stacks) [SCM_STACK_GROWS_UP]: Correction
	to stack marking call, two parameters and no cast on t->base.

2004-05-18  Marius Vollmer  <mvo@zagadka.de>

	* hashtab.c (rehash_after_gc): Bug fix: properly link the
	processed hashtables back into the weak_hashtables list.  Thanks
	to Bill Schottstaedt!

2004-05-16  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* eval.c (unmemoize_quote): New static function.

	(scm_m_quote, scm_m_atslot_ref, SCM_CEVAL): Changed the byte code
	representation of 'quote' and '@slot-ref' to an improper list.
	This reduces execution time, the number of cells used to hold the
	memoized code, and thus also reduces garbage collection time.

	(scm_unmemocopy): Use unmemoize_quote for quote expressions.

	(SCM_CEVAL): Changed macro handling to also work with macros that
	return improper lists.  Added an assertion, that the code returned
	by a macro transformer will not lead to cycles in the memoized
	code.

2004-05-15  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	No functional change, just rearrangements of functions within the
	file.

	* eval.c (scm_ilookup, scm_unbound_variable_key,
	error_unbound_variable, scm_lookupcar1, scm_lookupcar): Moved to
	the definitions used for execution, since that's where they will
	belong to later.

2004-05-15  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* numbers.h (SCM_SLOPPY_FRACTIONP): Removed.  It was not used
	throughout guile, has not been part of an official release yet,
	and the concept of sloppy predicates has never been a good idea.

	(SCM_FRACTION_NUMERATOR, SCM_FRACTION_DENOMINATOR,
	SCM_FRACTION_SET_NUMERATOR, SCM_FRACTION_SET_DENOMINATOR):
	Simplified.

2004-05-15  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* throw.c (SETJBJMPBUF, SCM_SETJBDFRAME): Add cast to scm_t_bits
	to make explicit what happens.

2004-05-15  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* dynl.c (SET_DYNL_HANDLE): Add cast to scm_t_bits to make
	explicit what happens.

	* guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than
	SCM_SET_CELL_WORD_x when writing scheme objets to cell elements.

2004-05-11  Marius Vollmer  <mvo@zagadka.de>

	* scmsigs.c (scm_sigaction_for_thread): Validate that the handler
	is indeed a procedure when it isn't a number.

2004-05-10  Marius Vollmer  <mvo@zagadka.de>

	Convert floating point numbers into strings with an arbitrary
	radix.  Thanks to Richard Todd!
	
	* numbers.c (FLOBUFLEN): Increase so that radix 2 strings will
	fit.
	(fx): Removed.
	(scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix,
	number_chars): New, to support variable radices.
	(idbl2str): Use above instead of the old base-10 only tables.
	(iflo2str): Pass on new RADIX argument to idbl2str.
	(scm_number_to_string): Pass radix to iflo2str.
	(scm_print_real, scm_print_complex): Explicitly pass radix 10 to
	iflo2str.
	(scm_init_numbers): Call init_dblprec and init_fx_radix for all
	possible radices.

2004-05-10  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_logbit_p): Correction to test above the end of an
	inum.  Reported by Jan Konecny.

2004-05-06  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* gc.h (scm_t_cell): Fields are now of type SCM instead of
	scm_t_bits.  Updated all users.
	(SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of
	duplicating the code.
	(SCM_CELL_OBJECT_LOC): New.
	(SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
	(SCM_CELL_WORD_LOC): Moved to "deprecated.h".

	* smob.h (SCM_SMOB_DATA_2, SCM_SMOB_DATA_3, SCM_SMOB_FLAGS,
	SCM_SET_SMOB_DATA_2, SCM_SET_SMOB_DATA_3, SCM_SET_SMOB_FLAGS,
	SCM_SMOB_OBJECT, SCM_SMOB_OBJECT_2, SCM_SMOB_OBJECT_3,
	SCM_SET_SMOB_OBJECT, SCM_SET_SMOB_OBJECT_2, SCM_SET_SMOB_OBJECT_3,
	SCM_SMOB_OBJECT_LOC, SCM_SMOB_OBJECT_2_LOC,
	SCM_SMOB_OBJECT_3_LOC): New.
	* smob.c (scm_i_set_smob_flags): New function.

	* dynl.c, dynwind.c, eval.h, fluids.h, futures.h, hashtab.h,
	hooks.h, keywords.h, macros.h, macros.c, mallocs.c, mallocs.h,
	random.h, regex-posix.h, root.h, srcprop.h, srcprop.c, threads.h:
	Use SCM_SMOB_* instead of SCM_CELL_* as appropriate.  Use
	SCM_SMOB_FLAGS and SCM_SET_SMOB_FLAGS instead of accessing the
	zeroth word directly.  Use SCM_SMOB_PREDICATE as appropriate.

	* numbers.h (SCM_I_BIG_MPZ): Use SCM_CELL_OBJECT_LOC instead of
	taking the address of SCM_CELL_WORD_1, the latter being no longer
	an lvalue.

	* variable.h (SCM_VARIABLE_LOC): Use SCM_CELL_OBJECT_LOC instead
	of casting SCM_CELL_WORD_LOC.

2004-05-02  Kevin Ryde  <user42@zip.com.au>

	* eval.c (scm_macroexp): Add prototype, since it's not in eval.h under
