* libguile/ephemerons.c (scm_from_ephemeron, scm_to_ephemeron): (scm_from_ephemeron_table, scm_to_ephemeron_table): New interfaces. (scm_c_ephemeron_table_copy): Rename from scm_c_ephemeron_hash_table_copy, as it's not specific to hash tables. * libguile/fluids.h: * libguile/fluids.c (restore_dynamic_state, save_dynamic_state) (saved_dynamic_state_ref, fluid_set_x, fluid_ref) (scm_fluid_ref_star, scm_i_make_initial_dynamic_state): Use ephemeron hash tables.
