Declaration removed.
(scm_t_contregs): New "fresh" field.
* continuations.c (ia64_getcontext): Removed.
(scm_make_continuation): Use continuation fresh field instead of
interpreting getcontext return values (which isn't portable). Use

instead of Linux-specific implementations.
(copy_stack_and_call): Use scm_ia64_register_backing_store_base()
instead of Linux-specific implementation.
* _scm.h (__ia64__): Also detect __ia64.
(scm_block_gc, scm_gc_heap_lock): Removed. Removed all uses.
(scm_gc_running_p): Now a macro that refers to the scm_i_thread
field.
(scm_i_sweep_mutex): Now a non-recursive mutex. GC can not happen
recursively.
(scm_igc, scm_i_gc): Renamed former to latter. Changed all uses.
Do not lock scm_i_sweep_mutex, which is now non-recursive, or set
scm_gc_running_p. Do not run the scm_after_gc_c_hook.
(scm_gc): Lock scm_i_sweep_mutex, set scm_gc_running_p and run the
scm_after_gc_c_hook here.
(scm_gc_for_new_cell): Set scm_gc_running_p here and run the
scm_after_gc_c_hook when a full GC has in fact been performed.
(scm_i_expensive_validation_check): Call scm_gc, not scm_i_gc.
* gc-segment.c (scm_i_get_new_heap_segment): Do not check
scm_gc_heap_lock.
* gc-malloc.c (scm_realloc, increase_mtrigger): Set
scm_gc_running_p while the scm_i_sweep_mutex is locked.

duplicating the code.
(SCM_CELL_OBJECT_LOC): New.
(SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
(SCM_CELL_WORD_LOC): Moved to "deprecated.h".
before converting to unsigned int. This prevents hi-bit ascii as
being converted large integers.
(string_upcase_x): change caller for scm_{up,down}case to
scm_c_{up,down}case
* chars.h (scm_init_chars): change scm_{upcase,downcase} to
scm_c_{up,down}case.
(SCM_MAKE_CHAR): add (unsigned char) cast. This prevents havoc
when hi-bit ASCII is subjected to SCM_MAKE_CHAR().
* configure.in: Removed -lm check and added a cached check for
__libc_stack_end to get it building for mingw32 hosts.
2003-05-29 Stefan Jahn <stefan@lkcc.org>
* win32-dirent.c: Use malloc() instead of scm_malloc().

warning.
* posix.c (s_scm_putenv): Disable use of unsetenv() for the
mingw32 build.
* modules.c (s_scm_module_import_interface): Renamed local
variable interface to _interface. Seems like 'interface'
is a special compiler directive for the mingw32 compiler.

path detections for native Windows platforms.
* gc.h, threads.h: Export some more symbols using SCM_API
(necessary to build on mingw32).

libguile_srfi_srfi_4_la_LDFLAGS,
libguile_srfi_srfi_13_14__la_LDFLAGS): Added the -no-undefined
option for the mingw32 build.
2003-05-29 Stefan Jahn <stefan@lkcc.org>
* standalone/Makefile.am: Setup to build on mingw32.
SCM_SIZEOF_UNSIGNED_LONG. Replace usage of USE_PTHREAD_THREADS
with SCM_USE_PTHREAD_THREADS. Remove SCM_SIZEOF_LONG definition
since we handle that in scmconfig.h now.

leaf_environment_fold, obarray_remove_all): Use hashtable
accessors.

* symbols.c, symbols.h (scm_i_hash_symbol): New function.
* weaks.c, weaks.h (scm_make_weak_key_alist_vector,
scm_make_weak_value_alist_vector,
scm_make_doubly_weak_alist_vector): New functions.
* weaks.c (scm_init_weaks_builtins): New function.
* weaks.h (SCM_WVECTF_WEAK_KEY, SCM_WVECTF_WEAK_VALUE,
SCM_WVECTF_NOSCAN, SCM_WVECT_WEAK_KEY_P, SCM_WVECT_WEAK_VALUE_P,
SCM_WVECT_NOSCAN_P): New macros.
* weaks.c (scm_scan_weak_vectors): Use SCM_WVECT_WEAK_KEY_P
and SCM_WVECT_WEAK_VALUE_P.

(module-map): Use hash-map.
* gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
scm_gc_register_collectable_memory): Substitute locking of
scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
(scm_igc): Lock sweep mutex here instead of in callers; Calls to
scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
the single-thread section (which now only contains the mark
phase).
(scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
* threads.c (gc_section_mutex): Removed.
* gc-malloc.c (malloc_mutex): New mutex.
(scm_gc_malloc_prehistory): Initialize it.
(scm_realloc): Serialize call to realloc
(scm_calloc): Same for calloc.
Thanks to Wolfgang Jaehrling!
(Now we have to make sure all calls to malloc/realloc are made
through scm_malloc.)
* init.c (scm_init_guile_1): Call scm_gc_malloc_prehistory.
(SCM_NONREC_CRITICAL_SECTION_START,
SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,

* gc-freelist.c, threads.c (really_launch): Use
SCM_FREELIST_CREATE.
* gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):
* gc.c (scm_i_expensive_validation_check, scm_gc,
scm_gc_for_newcell): Put threads to sleep before doing GC-related
heap administration so that those pieces of code are executed
single-threaded. We might consider rewriting these code sections
in terms of a "call_gc_code_singly_threaded" construct instead of
calling the pair of scm_i_thread_put_to_sleep () and
scm_i_thread_wake_up (). Also, we would want to have as many of
these sections eleminated.
* init.c (scm_init_guile_1): Call scm_threads_prehistory.
* inline.h: #include "libguile/threads.h"
* pthread-threads.h: Macros now conform more closely to the
pthreads interface. Some of them now take a second argument.
* threads.c, threads.h: Many changes.
* configure.in: Temporarily replaced "copt" threads option with new
option "pthreads".
(USE_PTHREAD_THREADS): Define if pthreads configured.
* gc-malloc.c (scm_calloc): try to use calloc() before calling
scm_realloc().

init loop; handle this from scm_init_card_freelist()
* gc-card.c (scm_init_card_freelist): init bit vector here.

* gc.c (scm_i_expensive_validation_check): separate expensive
validation checks from cheap ones.
* vectors.c (s_scm_vector_move_right_x): remove side effect in
macro arg.
(s_scm_vector_move_left_x): idem.
* net_db.c, posix.c, socket.c: variable naming: change ans to
result.
* sort.c (scm_merge_vector_x): accept vector as argument
iso. SCM*. This is needed for full GC correctness.
* gc.h: undo previous undocumented changes related to #ifdef
GENGC.
* *.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.

vectors.c, weaks.c: Use scm_gc_malloc/scm_malloc and
scm_gc_free/free instead of scm_must_malloc and scm_must_free, as
appropriate. Return zero from smob and port free functions.
* debug-malloc.c (scm_malloc_reregister): Handle "old == NULL".
* fports.c (scm_setvbuf): Reset read buffer to saved values when
it is pointing to the putback buffer.
SCM_GC_SET_CELL_WORD, SCM_GC_SET_CELL_OBJECT): New macros.
(SCM_GC_CELL_TYPE, SCM_CELL_WORD, SCM_CELL_OBJECT,
SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT, SCM_FREE_CELL_CDR,

macros.
(SCM_FREE_CELL_P): Express in terms of SCM_GC_CELL_TYPE.
