2001-02-11  Marius Vollmer  <mvo@zagadka.ping.de>

	Fix evaluator so that top-level expressions are correctly
	evaluated with respect to the module system.
	
	* modules.h. modules.c (scm_current_module_lookup_closure): New
	function.

	* eval.h (scm_primitive_eval, scm_primitive_eval_x): New
	prototypes.
	(scm_i_eval, scm_i_eval_x, scm_eval, scm_eval_x): Changed argument
	names to better reflect their meaning.

	* eval.c (scm_ceval, scm_deval): Recognize when `begin' is being
	evaluated at top-level and synronize lookup closure before
	executing every subform.
	(scm_primitve_eval_x, scm_primitive_eval): New functions.
	(scm_eval_x, scm_eval): Reimplement in terms of
	scm_primitive_eval_x and scm_primitive_eval, respectively.
	
2001-02-09  Marius Vollmer  <mvo@zagadka.ping.de>

	* macros.c (scm_macro_name, scm_macro_transformer): Use
	SCM_SMOB_DATA instead of SCM_CDR.  Provided by Martin Grabmueller.
	Thanks!

2001-02-10  Keisuke Nishida  <kxn30@po.cwru.edu>

	* dump.c (scm_store_bytes): Store data size before data.
	(scm_restore_bytes): Restore data size.  Takes a pointer to size.
	* dump.h (scm_restore_bytes): Updated.

2001-02-09  Keisuke Nishida  <kxn30@po.cwru.edu>

	* dump.c: Use double cells for update schedule.

2001-02-08  Keisuke Nishida  <kxn30@po.cwru.edu>

	* ports.c (scm_unread_char): Take an optional argument.

2001-02-08  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* 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.

2001-02-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* strings.h (SCM_STRING_MAX_LENGTH):  New macro.

	* strings.c (scm_makstr, scm_take_str, scm_make_string):  Added
	range checking for the size parameter.  Thanks to Martin
	Grabmueller for the hint.

	deferring unnecessary.

2001-02-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* vectors.h (SCM_VECTOR_MAX_LENGTH):  New macro.

	* vectors.c (scm_make_vector, scm_c_make_vector):  Improved the
	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.

	shown, and that parameter types are only checked once.
