integer (assuming for now accepting an integer is a good thing).
* error.c, fports.c: replace use of %S in lgh_error args with %s.
%S will be used instead for write'ing arguments.
* unif.c (scm_transpose_array): change arguments in the SCM_WNA
asserts. fix a few other asserts.
(scm_aind, scm_enclose_array, scm_array_in_bounds_p,
scm_uniform_vector_ref, scm_array_set_x,
scm_dimensions_to_unform_array): change args in
SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
scm_substring_fill_x): likewise.
gsubr.c (scm_gsubr_apply): likewise.
eval.c (SCM_APPLY): likewise.
* eval.c (4 places): replace scm_everr with lgh_error or
scm_wrong_num_args.
* error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
scm_memory_error): new procedures.
* scm_everr: deleted. can use scm_wta, dropping first two args.
scm_error: convert NULL subr to SCM_BOOL_F.
* __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
SCM_ARGERR.
* stackchk.c (scm_report_stack_overflow): use lgh_error instead
of scm_wta.
* error.c, error.h: new error keys: scm_arg_type_key,
scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
scm_misc_error_key.
scm_wta: reimplement using lgh_error instead of scm_everr.
argument pairs. Extensive modifications to the debugging
evaluator. Added "SECTION:" commentaries to clarify what happens
when, during double compilation. Renamed EVALIMP --> EVALIM.
Renamed EVAL --> XEVAL. Removed function evalcar. Defined
evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
the beginning of the file. New procedure: scm_unmemocopy.
Added some global state variables needed by the debugging
evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
check_entry, check_apply, check_exit, debug_options and
evaluator_traps. New acro: undefine.
