* libguile/tags.h (scm_tc7_array): Allocate a tag for arrays. * libguile/arrays.h (SCM_I_ARRAYP): Change to use scm_tc7_array. The previous definition was not externally usable because scm_i_tc16_array was internal. (scm_i_print_array): Declare, though internally. * libguile/arrays.c (scm_i_make_array): Use scm_cell with the tc7 instead of NEWSMOB. (scm_i_print_array): Make not static. (SCM_ARRAY_IMPLEMENTATION): Adapt. (scm_init_arrays): Remove array smob declaration. * libguile/eq.c (scm_equal_p): Refactor to put the string, pointer, and bytevector cases in the switch. Add a case for arrays. * libguile/goops.c: Add <array> declarations. * libguile/print.c (iprin1): Call scm_i_print_array as needed. * libguile/evalext.c (scm_self_evaluating_p): Add a case for arrays.
