* hooks.c (scm_c_hook_add): Fixed bug in append mode.
* environments.c (obarray_enter, obarray_retrieve, obarray_remove, leaf_environment_fold, obarray_remove_all): Use hashtable accessors. * gc.c (scm_init_storage): Moved hook initialization to scm_storage_prehistory. (scm_storage_prehistory): New function. (scm_igc): Added commentary about placement of scm_after_sweep_c_hook. * gc-mark.c (scm_mark_all): Use hashtable accessors. (scm_gc_mark_dependencies): Use SCM_WVECT_WEAK_KEY_P and SCM_WVECT_WEAK_VALUE_P. * hashtab.c, hashtab.h (scm_hash_for_each, scm_hash_map): New functions. (scm_vector_to_hash_table, scm_c_make_resizing_hash_table): Removed. (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table): Moved here from weaks.c. * init.c (scm_init_guile_1): Removed call to scm_init_weaks; Added calls to scm_storage_prehistory and scm_hashtab_prehistory. * modules.c (module-reverse-lookup): Use hashtable accessors. * symbols.c, symbols.h (scm_i_hash_symbol): New function. * weaks.c, weaks.h (scm_make_weak_key_alist_vector, scm_make_weak_value_alist_vector, scm_make_doubly_weak_alist_vector): New functions. * weaks.c (scm_init_weaks_builtins): New function. * weaks.h (SCM_WVECTF_WEAK_KEY, SCM_WVECTF_WEAK_VALUE, SCM_WVECTF_NOSCAN, SCM_WVECT_WEAK_KEY_P, SCM_WVECT_WEAK_VALUE_P, SCM_WVECT_NOSCAN_P): New macros. * weaks.c (scm_scan_weak_vectors): Use SCM_WVECT_WEAK_KEY_P and SCM_WVECT_WEAK_VALUE_P. * weaks.c, weaks.h (scm_i_allocate_weak_vector): Renamed from allocate_weak_vector and exported. * Makefile.am (ice9_sources): Added weak-vector.scm. * weak-vector.scm: New file. * boot-9.scm (module-clear!): Use hash-clear!.
