+
+       Merge from mvo-vcell-clenaup-1-branch.
+       
+       The concept of vcells has been removed from Guile.  With it,
+       explicit obarrays and associated operations are gone.  Use
+       hashtables instead of obarrays.
+       
+       Throughout: use scm_sym2var instead of scm_sym2vcell and treat
+       result as variable instead of vcell.  Glocs no longer point to a
+       vcell but to a variable.  Use scm_c_define instead of
+       scm_sysintern and treat the result as a variable (which it is),
+       not a vcell.
+       
+       * variable.c, variable.h (SCM_VARVCELL, SCM_UDVARIABLEP,
+       SCM_DEFVARIABLEP): Deprecated.
+       (SCM_VARIABLE_REF, SCM_VARIABLE_SET, SCM_VARIABLE_LOC): New.
+       (variable_print): Do not print name of variable.
+       (variable_equalp): Compare values, not vcells.
+       (anonymous_variable_sym): Removed.
+       (make_vcell_variable): Removed.
+       (make_variable): New, as replacement.
+       (scm_make_variable, scm_make_undefined_variable): Do not take name
+       hint parameter.
+       (scm_variable_ref): Check for SCM_UNDEFINED and throw "unbound"
+       error in that case.
+       (scm_builtin_variable): Deprecated.
+
+       * symbols.c, symbols.h (scm_sym2vcell, scm_sym2ovcell_soft,
+       scm_sym2ovcell, scm_intern_obarray_soft, scm_intern_obarray,
+       scm_intern, scm_intern0, scm_sysintern0_no_module_lookup,
+       scm_sysintern, scm_sysintern0, scm_symbol_value0,
+       scm_string_to_obarray_symbol, scm_intern_symbol,
+       scm_unintern_symbol, scm_symbol_binding, scm_symbol_interned,
+       scm_symbol_bound_p, scm_symbol_set_x, scm_gentmp, gentmp_counter):
+       Deprecated and moved to "symbols-deprecated.c".
+       (copy_and_prune_obarray, scm_builtin_bindings): Removed.
+       (scm_init_symbols): Call scm_init_symbols_deprecated.
+       * symbols-deprecated.c: New file.
+       * Makefile.am: Added symbols-deprecated.c and related files in all
+       the right places.
+       
+       * snarf.h (SCM_VCELL, SCM_GLOBAL_VCELL, SCM_VCELL_INIT,
+       SCM_GLOBAL_VCELL_INIT): Deprecated.
+       (SCM_VARIABLE, SCM_GLOBAL_VARIABLE, SCM_VARIABLE_INIT,
+       SCM_GLOBAL_VARIABLE_INIT): New, as replacement.  Changed all uses.
+       
+       * print.c (scm_iprin1): Use scm_module_reverse_lookup instead of
+       SCM_GLOC_SYM.
+
+       * evalext.c, filesys.c, fports.c, gdbint.c, gh_data.c, gsubr.c,
+       hooks.c, load.c, numbers.c, objects.c, ports.c, posix.c, procs.c,
+       ramap.c, random.c, read.c, regex-posix.c, scmsigs.c, script.c,
+       socket.c, srcprop.c, stacks.c, stime.c, struct.c, tag.c, throw.c:
+       Changed according to the `throughout' comments.
+
+       * modules.h, modules.c (scm_module_system_booted_p): Changed type
+       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.
+       (scm_the_root_module): Return SCM_BOOL_F when module systems
+       hasn't been booted yet.
+       (SCM_VALIDATE_STRUCT_TYPE): Removed.
+       (scm_post_boot_init_modules): Made static.
+       (scm_set_current_module): Call scm_post_boot_init_modules on first
+       call.
+       (make_modules_in, beautify_user_module_x, resolve_module,
+       try_module_autoload, module_make_local_var_x): Tacked on "_var"
+       suffix.  Now point to variables instead of vcells.  Updated all
+       uses.
+       (scm_module_lookup_closure): Deal with the module being SCM_BOOL_F
+       and return SCM_BOOL_F in that case.
+       (scm_module_transformer): Likewise.
+       (sym_module, scm_lookup_closure_module, scm_env_module): New.
+       (SCM_F_EVAL_CLOSURE_INTERFACE, SCM_EVAL_CLOSURE_INTERFACE_P): New.
+       (scm_eval_closure_lookup): Do not allow new definitions when
+       `interface' flag is set.
+       (scm_standard_interface_eval_closure): New.
+       (scm_pre_modules_obarray, scm_sym2var, scm_module_lookup,
+       scm_lookup, scm_module_define, scm_define, scm_c_module_lookup,
+       scm_c_lookup, scm_c_module_define, scm_c_define,
+       scm_module_reverse_lookup, scm_get_pre_modules_obarray,
+       scm_modules_prehistory): New.
+       (scm_post_boot_init_modules): Use scm_c_define and scm_c_lookup
+       instead of scm_intern0.
+       
+       * macros.c (scm_make_synt): Return SCM_UNSPECIFIED instead of the
+       symbol.
+
+       * keywords.c (s_scm_make_keyword_from_dash_symbol): Use a regular
+       hashtable operations to maintain the keywords, not obarray ones.
+
+       * init.c (scm_load_startup_files): Do not call
+       scm_post_boot_init_modules.  This is done by
+       scm_set_current_module now.
+       (scm_init_guile_1): Call scm_modules_prehistory.  Call
+       scm_init_variable early on.
+
+       * goops.c (s_scm_sys_goops_loaded): Get
+       var_compute_applicable_methods from scm_sym2var, not from a direct
+       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
+       activated, do not tail-call scm_gc_mark.  This gives nice
+       backtraces.
+       (scm_unhash_name): Removed.
+
+       * feature.c (features): Renamed to features_var.  Now points to a
+       variable instead of a vcell.  Updated all uses.
+
+       * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): Use
+       `scm_current_module_lookup_closure' which will do the right thing
+       when the module system hasn't been booted yet.
+       (SCM_GLOC_SYM): Removed.
+       (SCM_GLOC_VAR, SCM_GLOC_SET_VAL): New.
+       (SCM_GLOC_VAL, SCM_GLOC_LOC): Reimplemented in terms of variables.
+       
+       * eval.c (scm_lookupcar, scm_lookupcar1): Deal with variables
+       instead of with vcells.  Do not overwrite `var' with the result of
+       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.
+       (s_scm_gloc_p): Use `scm_tc3_cons_gloc' instead of the magic `1'.
+       (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.
+
+       * root.h (scm_symhash, scm_symhash_vars): Removed.
+       * gc.c (scm_init_storage): Do not initialize them.
+

        * eval.c (scm_init_eval):  Initialize scm_undefineds and
