* New file gc-segment-table.c: hold code for the segment table.
* Remove data that might be out of date; remove
scm_i_adjust_min_yield(). We don't store min_yields, since they
are only accurate at one point in time (when the sweep finishes).
We decide the min yield at that point from min_yield_fraction and
freelist->collected / freelist->swept
* Introduce scm_i_gc_heap_size_delta() replacing
scm_i_gc_grow_heap_p().
* Remove foo_1 fields containing penultimate results.
* After GC, count mark bit vector to discover number of live
objects. This simplifies hairy updates.
* Many formatting and layout cleanups.
* Fix in scm_i_sweep_card(): return the length of free_list returned,
rather than number of deleted objects.
* For mtrigger GCs: do not also run a full sweep after the gc() call, as
this is inconsistent with lazy sweeping.
* Remove scm_i_make_initial_segment().
* Use calloc in scm_i_make_empty_heap_segment() to save on
initialization code.
* New function scm_i_sweep_for_freelist() which sweeps, with proper
statistic variable updates.
* New segments are conceptually blocks with 100% reclaimable cells.
* Remove some useless constants/comments: SCM_HEAP_SIZE,
SCM_INIT_HEAP_SIZE, SCM_EXPHEAP, SCM_HEAP_SEG_SIZE
* Do not increment scm_cells_allocated() from the
scm_[double]cell(). This would be a race condition.
* Move some deprecation checks in separate functions to not distract
from main code flow.
* configure.in: Removed -lm check and added a cached check for
__libc_stack_end to get it building for mingw32 hosts.

* win32-dirent.c: Use malloc() instead of scm_malloc().
* stime.c (s_scm_strftime): Add a type cast to avoid compiler
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.
* mkstemp.c: Provide prototype to avoid compiler warning.
* load.c (s_scm_search_path): Fixed absolute and relative
path detections for native Windows platforms.
* gc.h, threads.h: Export some more symbols using SCM_API
(necessary to build on mingw32).
* gc-freelist.c ("s_scm_map_free_list",
"s_scm_gc_set_debug_check_freelist_x"): Fixed use of FUNC_NAME.
* fports.c (fport_fill_input): Disable use of
fport_wait_for_input() on Win32 platforms.
* filesys.c (s_scm_basename): Fixed __MINGW32__ code.
* Makefile.am: Modified some rules for cross compiling.
2003-05-29 Stefan Jahn <stefan@lkcc.org>
* raw-ltdl.c: Some more modifications for mingw32 platforms.
2003-05-29 Stefan Jahn <stefan@lkcc.org>
* Makefile.am (libguile_srfi_srfi_1_la_LDFLAGS,
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_NONREC_CRITICAL_SECTION_START,
SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
SCM_REC_CRITICAL_SECTION_END): New macros.
(SCM_CRITICAL_SECTION_START/END): Defined here.
* eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
the three calls to scm_m_expand_body.
* gc.h: #include "libguile/pthread-threads.h";
(SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.
* gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type
scm_t_key;
* gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
access.
* gc-freelist.c (scm_gc_init_freelist): Create freelist keys.
* 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.
for sanity.
* gc-malloc.c (scm_gc_init_malloc): check user settings for
sanity.
(scm_gc_register_collectable_memory): prevent overflow of memory
counts.
* gc-freelist.c (scm_init_freelist): check user settings for sanity.
* gc-malloc.c (scm_gc_register_collectable_memory): use floats;
these won't ever wrap around with high memory usage.
* gc-freelist.c: include <stdio.h>
* gc-malloc.c: add DEBUGINFO for mtrigger GCs.
