associated with subrs. (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS, SCM_SUBR_DOC): New macros. (scm_subr_table): New variable. (scm_mark_subr_table): New function. * init.c (scm_boot_guile_1): Call scm_init_subr_table. * gc.c (scm_gc_mark): Don't mark subr names here. (scm_igc): Call scm_mark_subr_table. * snarf.h (SCM_GPROC, SCM_GPROC1): New macros. * procs.c, procs.h (scm_subr_p): New function (used internally). * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function. * objects.c, objects.h (scm_primitive_generic): New class. * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros. * print.c (scm_iprin1): Print primitive-generics. * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1, SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros. * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta --> SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point primitives). NOTE: This means that it is now *required* to use SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an obscured representation that will be removed in the future anyway, so backward compatibility is no problem here). * numbers.c: Converted most numeric primitives (all but bit comparison operations and bit operations) to dispatch on generic if args don't match. * eval.c, eval.h (scm_eval_body): New function. * objects.c (scm_call_generic_0, scm_call_generic_1, scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New functions. * eval.c (SCM_CEVAL): Apply the cmethod directly after having called scm_memoize_method instead of doing a second lookup. * objects.h (scm_memoize_method): Now returns the memoized cmethod. * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of scm_sysintern so that the binding connected with the subr name isn't cleared when we give set = 0.
