	Enclosed arrays are now their own smob.  This has been done to
	make the code more explicit about them and to prepare for the time
	when generalized vectors include arbitrary one-dimensional
	arrays. (Uptonow, enclosed arrays have been recognized by their
	use of an array as their storage 'vector'.  When all generalized
	vectors are allowed as storage, including one-dimensional arrays,
	this will no longer work.)
	
	* unif.h, unif.c: (scm_tc16_enclosed_array, SCM_ENCLOSED_ARRAYP):
	New.
	(exactly_one_third, singp): Removed.
	(scm_array_p, scm_array_dimensions, scm_shared_array_root,
	scm_shared_array_offset, scm_shared_array_increments): Handle
	enclosed arrays explicitely.
	(scm_array_rank): Likewise. Also, do not return zero for
	non-arrays, signal an error instead since arrays with rank zero do
	exist.
	(scm_i_make_ra): New, for specifying the tag of the new array.
	(scm_make_enclosed_array): Use it.
	(scm_make_ra): Reimplemented in terms of scm_i_make_ra.
	(scm_make_shared_array): Use scm_c_generalized_vector_length
	instead of scm_uniform_vector_length.
	(scm_array_in_bounds_p): Rewritten to be much cleaner.
	(scm_i_cvref): New, doing the job of scm_cvref.
	(scm_cvref): Use scm_i_cvref.
	(scm_array_ref): Do not accept non-arrays when no indices are
	given. Use scm_i_cvref to do the actual access.
	("uniform-array-set1"): Do not register.
	(scm_array_set_x, scm_uniform_array_read_x,
	scm_uniform_array_write): Handle enclosed arrays explicitly.
	(ra2l): Use scm_i_cvref instead of scm_uniform_vector_ref to also
	handle enclosed arrays.
	(scm_array_to_list): Handle enclosed arrays explicitly.
	(rapr1): Removed.
	(scm_i_print_array_dimension): Use scm_i_cvref to also handle
	enclosed arrays.
	(scm_i_print_enclosed_array): New.
	(tag_proto_table, tag_creator_table): Renamed former to latter.
	Added "a" and "b" for strings and bitvectors, resp.
	(scm_i_tag_to_prototype, scm_i_tag_to_creator): Renamed former to
	latter.  Tag "a" is in the table now, no need to handle it as a
	legacy tag.
	(scm_raprin1): Just call scm_iprin1.
	(scm_array_creator, scm_array_prototype): Handle enclosed arrays
	explicitly.
	(scm_init_unif): Initialize scm_tc16_enclosed_array smob.
	Use scm_i_print_array as printer for scm_tc16_array.

	* ramap.c (cind): Changed second arg to be pointer to long instead
	of uniform vector.
	(scm_ramapc): Allocate index vector with scm_malloc and not as
	uniform vector.  Wrap it in a frame so that it gets properly freed.
	(scm_array_index_map_x): Likewise.

	* unif.c: Changed all uses of scm_array_prototype to
	scm_array_creator. (scm_i_get_old_prototype): Signal error when no
	prototype is known.
	(scm_uniform_array_read_x, scm_uniform_array_write): Reimplemented
	in terms of scm_uniform_vector_read_x and
	scm_uniform_vector_write, respectively.  Strings and
	bitvector support has been dropped.
	
	* srfi-4.h, srfi-4.c: Do not include <libguile.h>, include the
	needed files directly.  Include config.h, <unistd.h> and <io.h>
	when available.
	(scm_uniform_vector_read_x, scm_uniform_vector_write): New.

2004-11-09  Marius Vollmer  <mvo@zagadka.de>

	* gh_data.c (gh_uniform_vector_length): Properly use

	(coerce_to_uvec): Use new generalized vector functions to handle
	all kinds of vectors in one go.
	
	* tags.h (scm_tc7_bvect): Renamed to scm_tc7_unused7, renaming the
	remaining scm_tc7_unused tags to get a neatly ordered list.

	* eq.c, evalext.c, gc-card.c, gc-mark.c, objects.c, print.c: Do no
	longer handle scm_tc7_bvect bitvectors.

	* ramap.c: Use the new generalized vector functions to handle all
	vector like things.

	* vectors.h, vectors.c (scm_is_vector, scm_c_vector_length,

	bitvector_equalp, count_ones, find_first_one): New.
	(scm_bit_count, scm_bit_position, scm_bit_set_star_x,
	scm_bit_count_star, scm_bit_invert_x, scm_istr2bve): Rewritten
	using the new C API for bitvectors and maybe count_ones or
	find_first_one, as appropriate.
	(SCM_I_MAX_LENGTH, SCM_BITVECTOR_P, SCM_BITVECTOR_BASE,
	SCM_SET_BITVECTOR_BASE, SCM_BITVECTOR_MAX_LENGTH,
	SCM_BITVECTOR_LENGTH, SCM_MAKE_BITVECTOR_TAG,
	SCM_SET_BITVECTOR_LENGTH): Removed.  Replaced all uses with the
	new functions from above.
	(scm_i_proc_make_vector, scm_i_proc_make_string,
	scm_i_proc_make_bitvector): Made non-static for use in
	scm_i_generalized_vector_creator.

	for "space".  Thanks to Bruce Korb!

	only after dest has been set.  Thanks to Hyper Division!

	* gh_data.c (gh_uniform_vector_length): Use
