* libguile/root.h
* libguile/root.c (scm_sys_protects): It used to be that for some reason
we'd define a special array of "protected" values. This was a little
silly, always, but with the BDW GC it's completely unnecessary. Also
many of these variables were unused, and none of them were good API.
So remove this array, and either eliminate, make static, or make
internal the various values.
* libguile/snarf.h: No need to generate calls to scm_permanent_object.
* guile-readline/readline.c (scm_init_readline): No need to call
scm_permanent_object.
* libguile/array-map.c (ramap, rafe): Remove the dubious nullvect
optimizations.
* libguile/async.c (scm_init_async): No need to init scm_asyncs, it is
no more.

no more.

(scm_storage_prehistory): Change the sanity check to use the address
of protects.
(scm_init_gc_protect_object): No need to clear the scm_sys_protects,
as it is no more.
* libguile/keywords.c: Make the keyword obarray a static var.
* libguile/numbers.c: Make flo0 a static var.
* libguile/objprop.c: Make object_whash a static var.

linkage.
* libguile/strings.h:
* libguile/strings.c: Make scm_nullstr a global with internal linkage.
* libguile/vectors.c (scm_init_vectors): No need to init scm_nullvect,
it's unused.
* libguile/__scm.h (scm_async_tick): New declaration.
(SCM_ASYNC_TICK)[!BUILDING_LIBGUILE]: Use `scm_async_tick ()'.
* libguile/async.c (scm_critical_section_start,
scm_critical_section_end, scm_async_tick): New functions.
* libguile/async.h (scm_i_critical_section_mutex): Made internal.

declarations.

SCM_CRITICAL_SECTION_END)[!BUILDING_LIBGUILE]: Use the same-named
function (lower-case).
* libguile/stackchk.h (SCM_STACK_OVERFLOW_P): Conditionalize on
`BUILDING_LIBGUILE'.
* libguile/threads.h (SCM_I_CURRENT_THREAD, scm_i_dynwinds,
scm_i_set_dynwinds, scm_i_last_debug_frame,
scm_i_set_last_debug_frame): Conditionalize on `BUILDING_LIBGUILE'.
This fixes bug #24009 reported by Martin Pitt.
* libguile/threads.c (guilify_self_1): Check the return value of
pipe(2).
(scm_std_select): Use `full_read ()' instead of `read ()' when reading
from WAKEUP_FD.
* libguile/async.c (scm_i_queue_async_cell): Use `full_write ()' instead
of write(2) when writing to SLEEP_FD.
* libguile/fports.c (fport_flush): Likewise.
* libguile/posix.c (getgroups): Use the return value of getgroups(2) as
NGROUPS.
(scm_nice): Get the return value of nice(2) to make glibc happy.
* libguile/scmsigs.c (take_signal): Use `full_write ()' instead of
write(2).
SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into "deprecated.h".
Replaced all uses with scm_is_false, scm_is_true, scm_from_bool, and
scm_is_bool, respectively.
signal_asyncs. Don't set cdr of a non-signal async to #f.
(scm_i_queue_async_cell): Do not check cdr of cell for #f, queue
always. Set pending_asyncs.
(scm_system_async_mark_for_thread): Check that thread has not
exited.
(scm_unmask_signals, decrease_block): Call scm_async_click after
block_asyncs becomes zero.
scm_i_thread_root when USE_THREADS is defined. Use scm_root
otherwise.
* scmsigs.c (take_signal): Only call scm_i_thread_root when
USE_THREADS is defined. Use scm_root otherwise.
(scm_sigaction_for_thread): Ignore THREAD argument when
USE_THREADS is not defined. Also, move THREAD argument defaulting
out of HAVE_SIGACTION section, which was a bug.
scm_call_with_unblocked_asyncs, scm_c_call_with_blocked_asyncs,
scm_c_call_with_unblocked_asyncs): New prototypes.
(scm_mask_signals, scm_unmask_signals): Deprecated.
(scm_mask_ints): Turned into a macro.
* async.c (scm_mask_ints): Removed.
(scm_run_asyncs): Do not set scm_mask_ints while running an async.
this should not be necessary.
(scm_async_click): Test block_asyncs instead of scm_mask_ints.
(scm_mask_signals, scm_unmask_signals): Deprecated. Emit
deprecation warning and check for errornous use. Set block_asyncs
instead of scm_mask_ints.
(increase_block, decrease_block, scm_call_with_blocked_asyncs,
scm_call_with_unblocked_asyncs, scm_c_call_with_blocked_asyncs,
scm_c_call_with_unblocked_asyncs): New.
cell to SCM_BOOL_F, not SCM_EOL.
(scm_i_queue_async_cell): Queue the cell at the end of the list,
and only if the handler procedure is not already present.
(scm_system_async_mark_for_thread): Initialize cdr of handler cell
with SCM_BOOL_F.
* scmsigs.c (scm_sigaction_for_thread): Likewise.
* *.c: add space after commas everywhere.
* *.c: use SCM_VECTOR_SET everywhere, where a vector is written.
Document cases where SCM_WRITABLE_VELTS() is used.
* vectors.h (SCM_VELTS): prepare for write barrier, and let
SCM_VELTS() return a const pointer
(SCM_VECTOR_SET): add macro.
* autogen.sh (mscripts): find and check version number of
autoconf. Complain if 2.53 is not found.
