2001-05-24  Michael Livshin  <mlivshin@bigfoot.com>

	The purpose of this set of changes is to regularize Guile's usage
	of ANSI C integral types, with the following ideas in mind:

	- SCM does not nesessarily have to be long.
	- long is not nesessarily enough to store pointers.
	- long is not nesessarily the same size as int.

	The changes are incomplete and possibly buggy.  Please test on
	something exotic.

	the new and shiny SCM_NUM2INT.

	* extensions.c: extension -> extension_t (and made a typedef).

213	the old name is deprecated, all in-Guile uses changed.
214	(scm_contregs_t.num_stack_items): size_t -> scm_bits_t
215	(scm_contregs_t.num_stack_items): ulong -> scm_ubits_t
216
217	* continuations.c (scm_make_continuation): change the type of
d69c867a	218	stack_size from long to scm_bits_t.
1be6b49c ML	219
	220	* ports.h: type renaming:
	221	scm_port_rw_active -> scm_port_rw_active_t (and made a typedef)
	222	scm_port -> scm_port_t
	223	scm_ptob_descriptor -> scm_ptob_descriptor_t
	224	the old names are deprecated, all in-Guile uses changed.
	225	(scm_port_t.entry): int -> scm_bits_t.
	226	(scm_port_t.line_number): int -> long.
	227	(scm_port_t.putback_buf_size): int -> size_t.
	228
	229	* __scm.h (long_long, ulong_long): deprecated (they pollute the
d69c867a	230	global namespace and have little value beside that).
1be6b49c ML	231	(SCM_BITS_LENGTH): new, is the bit size of scm_bits_t (i.e. of an
	232	SCM handle).
	233	(ifdef spaghetti): include sys/types.h and sys/stdtypes.h, if they
d69c867a	234	exist (for size_t & ptrdiff_t).
1be6b49c ML	235	(scm_sizet): deprecated.
	236
	237	* Makefile.am (noinst_HEADERS): add num2integral.i.c

	240
	241	* snarf.h (SCM_CONST_LONG): Use SCM_VCELL_INIT instead of
	242	SCM_VARIABLE_INIT since that it what it used to be.
	243
	244	* deprecation.c (scm_include_deprecated_features): Make docstring
