	explicit obarrays and associated operations are gone.  Use

	vcell but to a variable.  Use scm_c_define instead of

	to `int'.
	(scm_module_type): Removed.
	(the_root_module): Renamed to the_root_module_var.  Now points to
	a variable instead of a vcell.  Updated all uses.

	symbol.

	* keywords.c (s_scm_make_keyword_from_dash_symbol): Use a regular
	hashtable operations to maintain the keywords, not obarray ones.

	invocation of scm_goops_lookup_closure.

	* gh_funcs.c (gh_define): Return SCM_UNSPECIFIED instead of vcell.

	* gc.c: Added simple debugging hack to mark phase of GC: When

	the lookup, use the new `real_var' instead.  Remove `var2' in
	exchange (which was only used with threads).
	(sym_three_question_marks): New.
	(scm_unmemocar): Use `scm_module_reverse_lookup' instead of
	`SCM_GLOC_SYM'.
	(scm_lisp_nil, scm_lisp_t): Directly define as symbols.
	(scm_m_atfop): Expect the function definition to be a variable
	instead of a vcell.
	(scm_macroexp): Do not use `unmemocar', explicitely remember the
	symbol instead.
	(scm_unmemocopy): Removed thoughts about anti-macro interface.
	(scm_eval_args): Use more explicit code in the gloc branch of the
	atrocious struct ambiguity test.  The optimizer will sort this
	out.
	(scm_deval_args): Likewise.
	(SCM_CEVAL): Likewise.  Also, do not use unmemocar, explicitely
	remember the symbol instead.  Added some comments where
	scm_tc3_cons_gloc really exclusively refers to structs.
	(scm_init_eval): Use scm_define to initialize "nil" and "t" to
	scm_lisp_nil and scm_lisp_t, respectively.  Use scm_define instead
	of scm_sysintern in general.

	* dynwind.c (scm_swap_bindings): Use SCM_GLOC_SET_VAL instead of
	explicit magic.

	* debug.c (s_scm_make_gloc): Only allow proper variables, no
	pairs.  Put the variable directly in the gloc.

	(scm_init_debug): Use scm_c_define instead scm_sysintern.

	* cpp_cnvt.awk: Emit "scm_c_define" instead of "scm_sysintern".

	* backtrace.h, backtrace.c (scm_the_last_stack_fluid): Renamed to
	scm_the_last_stack_fluid_var.  It now points to a variable instead
	of a vcell.  Updated all uses.
	(scm_has_shown_backtrace_hint_p_var): Now points to a variable
	instead of a vcell.  Updated all uses.

	* _scm.h: Include "variables.h" and "modules.h" since almost
	everybody needs them now.

	scm_tc16_allocated from scm_init_gc to scm_init_storage.

	(scm_init_storage):  Moved initialization of scm_undefineds and
	scm_listofnull to eval.c, initializion of scm_nullstr to
	strings.c, initializion of scm_nullvect to vectors.c.

	* gc.h (SCM_NEWCELL, SCM_NEWCELL2):  Prefer SCM_NULLP over
	SCM_IMP, as in scm_debug_newcell and scm_debug_newcell2.

887dfa7d	160
f3f9dcbc MV	161	The concept of vcells has been removed from Guile. With it,
	162	explicit obarrays and associated operations are gone. Use
	163	hashtables instead of obarrays.
887dfa7d	164
f3f9dcbc MV	165	Throughout: use scm_sym2var instead of scm_sym2vcell and treat
	166	result as variable instead of vcell. Glocs no longer point to a
	167	vcell but to a variable. Use scm_c_define instead of
	168	scm_sysintern and treat the result as a variable (which it is),
	169	not a vcell.

	225	try_module_autoload, module_make_local_var_x): Tacked on "_var"
	226	suffix. Now point to variables instead of vcells. Updated all

	245	symbol.
	246

	248	hashtable operations to maintain the keywords, not obarray ones.
	249
	250	* init.c (scm_load_startup_files): Do not call
	251	scm_post_boot_init_modules. This is done by
	252	scm_set_current_module now.
	253	(scm_init_guile_1): Call scm_modules_prehistory. Call
	254	scm_init_variable early on.
	255
	256	* goops.c (s_scm_sys_goops_loaded): Get
	257	var_compute_applicable_methods from scm_sym2var, not from a direct
	258	invocation of scm_goops_lookup_closure.
	259
	260	* gh_funcs.c (gh_define): Return SCM_UNSPECIFIED instead of vcell.
	261
	262	* gc.c: Added simple debugging hack to mark phase of GC: When

	280	exchange (which was only used with threads).
	281	(sym_three_question_marks): New.
	282	(scm_unmemocar): Use `scm_module_reverse_lookup' instead of
	283	`SCM_GLOC_SYM'.

	288	symbol instead.
	289	(scm_unmemocopy): Removed thoughts about anti-macro interface.
	290	(scm_eval_args): Use more explicit code in the gloc branch of the
	291	atrocious struct ambiguity test. The optimizer will sort this
	292	out.
	293	(scm_deval_args): Likewise.
	294	(SCM_CEVAL): Likewise. Also, do not use unmemocar, explicitely
	295	remember the symbol instead. Added some comments where
	296	scm_tc3_cons_gloc really exclusively refers to structs.
	297	(scm_init_eval): Use scm_define to initialize "nil" and "t" to
	298	scm_lisp_nil and scm_lisp_t, respectively. Use scm_define instead
	299	of scm_sysintern in general.
	300
	301	* dynwind.c (scm_swap_bindings): Use SCM_GLOC_SET_VAL instead of
	302	explicit magic.
	303
	304	* debug.c (s_scm_make_gloc): Only allow proper variables, no
	305	pairs. Put the variable directly in the gloc.
	306	(s_scm_gloc_p): Use `scm_tc3_cons_gloc' instead of the magic `1'.
	307	(scm_init_debug): Use scm_c_define instead scm_sysintern.
	308
	309	* cpp_cnvt.awk: Emit "scm_c_define" instead of "scm_sysintern".
	310
	311	* backtrace.h, backtrace.c (scm_the_last_stack_fluid): Renamed to
	312	scm_the_last_stack_fluid_var. It now points to a variable instead
	313	of a vcell. Updated all uses.

	315	instead of a vcell. Updated all uses.
	316
	317	* _scm.h: Include "variables.h" and "modules.h" since almost
	318	everybody needs them now.
	319
	320	* root.h (scm_symhash, scm_symhash_vars): Removed.
	321	* gc.c (scm_init_storage): Do not initialize them.

	334	(scm_init_storage): Moved initialization of scm_undefineds and
	335	scm_listofnull to eval.c, initializion of scm_nullstr to
	336	strings.c, initializion of scm_nullvect to vectors.c.
	337
	338	* gc.h (SCM_NEWCELL, SCM_NEWCELL2): Prefer SCM_NULLP over
	339	SCM_IMP, as in scm_debug_newcell and scm_debug_newcell2.
	340
	341	* init.c (scm_init_guile_1): Reordered some initializations and
	342	added dependcy information comments.
	343
	344	* load.c (scm_init_load): Use scm_nullstr.
	345
	346	* strings.c (scm_init_strings): Initialize scm_nullstr.
