* configure.in: add --disable-arrays option, probably temporary. * the following changes allow guile to be built with the array "module" omitted. some of this stuff is just tc7 type support, which wouldn't be needed if uniform array types were converted to smobs. * tag.c (scm_utag_bvect ... scm_utag_cvect): don't define unless HAVE_ARRAYS. (scm_tag): don't check array types unless HAVE_ARRAYS. * sort.c (scm_restricted_vector_sort_x, scm_sorted_p): remove the unused array types. * (scm_stable_sort, scm_sort): don't support vectors if not HAVE_ARRAYS. a bit excessive. * random.c (vector_scale, vector_sum_squares, scm_random_solid_sphere_x, scm_random_hollow_sphere_x, scm_random_normal_vector_x): don't define unless HAVE_ARRAYS. * gh_data.c (makvect, gh_chars2byvect, gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect, gh_doubles2dvect, gh_uniform_vector_length, gh_uniform_vector_ref): don't define unless HAVE_ARRAYS. (gh_scm2chars, gh_scm2shorts, gh_scm2longs, gh_scm2floats, gh_scm2doubles): don't check vector types if not HAVE_ARRAYS. * eq.c (scm_equal_p), eval.c (SCM_CEVAL), print.c (scm_iprin1), gc.c (scm_gc_mark, scm_gc_sweep), objects.c (scm_class_of): don't support the array types unless HAVE_ARRAYS is defined. * tags.h: make nine tc7 types conditional on HAVE_ARRAYS. * read.c (scm_lreadr): don't check for #* unless HAVE_ARRAYS is defined (this should use read-hash-extend). * ramap.c, unif.c: don't check whether ARRAYS is defined. * vectors.c (scm_vector_set_length_x): moved here from unif.c. call scm_uniform_element_size if HAVE_ARRAYS. vectors.h: prototype too. * unif.c (scm_uniform_element_size): new procedure. * init.c (scm_boot_guile_1): don't call scm_init_ramap or scm_init_unif unless HAVE_ARRAYS is defined. * __scm.h: don't define ARRAYS. * Makefile.am (EXTRA_libguile_la_SOURCES): unif.c and ramap.c moved here from libguile_la_SOURCES. * Makefile.am (ice9_sources): add arrays.scm. * boot-9.scm: load arrays.scm if 'array is provided. * arrays.scm: new file with stuff from boot-9.scm.
