%S will be used instead for write'ing arguments.

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.

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.
SCM-style errors. handle the case that an unexpected number
of args are supplied.
(%%system-errors): removed.
(error): redefine using a throw with key and 4 args.
('error): associate 'error, 'error-signal keys with
%%handle-system-error.
(%%default-error-handler): removed.
(signal-handler): throw with 4 args and use the error-signal key.
Create an error message instead of using numerical codes.
(%%bad-throw): call error instead of throw if key not found.
* boot-9.scm: initialize new error keys (see libguile/ChangeLog).
(%%handle-system-error key): check subr is not #f before printing.
Recognize %s (embed an argument using "display") and
%S (embed an argument using "write").
expressions; New functions: recsexpr, scm_lreadrecparen;
_scm_make_srcprops --> scm_make_srcprops
(scm_flush_ws): Removed updating of positions counters. This work
is already done by scm_gen_getc
scm_port_\1; Added mutator scm_set_port_filename_x (used when
loading source from non-file ports, which, e. g., happens when
using the Emacs interface).
wta for range errors (ASSERT still needs work).
* error.c, error.h (scm_out_of_range): new procedure.
* error.c, error.h (scm_out_of_range_key): new key.
* posix.c (scm_sync): #else was missing.
* error.c, error.h: append _key to names scm_num_overflow and
scm_system_error.
* __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
of consing an empty list.
(SCM_SYSERROR etc.): move into error.c, make them procedures instead
of macros, saves code and string space.
error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
lower case. Rename scm_syserror_m to scm_syserror_msg.
error.h: prototypes for new procedures.
* PLUGIN/guile.config (xtra_dependencies): add only libgh.a.
(xtra_cflags): just add -L../lgh
* PLUGIN/guile.libs: try -lgh -lguile
* Makefile.am (INCLUDES): add -I../ so that libguile/scmconfig.h can
be found when srcdir != build dir.
* PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.
* error.c, error.h: setup scm_num_overflow key.
* __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
Remove definition of SCM_OVSCM_FLOW.
* fports.c (scm_open_file): use SCM_SYSERROR_M.
* __scm.h: SCM_SYSERROR_M: new macro for system errors with an
explicit message and args.
* error.c, error.h, __scm.h: change system_error_sym to
scm_system_error.
* error.c (system_error_sym): remove leading %% from the Scheme name
"%%system-error".
* __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
* boot-9.scm: remove leading %% from references to '%%system-error.
(%%handle-system-error): don't pass all the thrown arguments when
aborting, just the key and subr.
Remove the code to "Install default handlers for built-in errors."
Remove the definition of the syserror procedure.
Associate 'numerical-overflow with default handler.
resolved-ref --> nested-ref Motivation: conformance to the other
dictionary operators: list-ref operates on list, vector-ref
operates on vector, nested-ref operates on nested namespace,
local-ref operates on the local nested namespace.
printing. (init_ref_stack, grow_ref_stack): New functions. Added
a hook for printing of closures (accessible via print options).
This leads to a split of calls to scm_iprin1 into two classes:
elementary print operations (e. g. the code which prints a smob)
still use scm_iprin1 while top level calls (like scm_display) use
scm_prin1. scm_prin1 begins by clearing the data structure used
to record reference information.
