(to_rehash): Removed.
(scm_internal_hash_fold): Use `SCM_WEAK_CELL_DELETED_P ()' rather than

SCM_DEBUG_MARKING_API crash if someone is touching markbits

for debugging if SCM_DEBUG_MARKING_API is unset
* libguile/gc-mark.c: Issue deprecation warning if we are marking
outside of the GC mark phase.
* libguile/gc-card.c: Include <config.h> and <count-one-bits.h>.

git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-32
* libguile/symbols.c (lookup_interned_symbol): When checking for `NULL',
use `SCM2PTR' rather than `SCM_UNPACK' (this fixes a warning).
git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-31
* libguile/smob.c (smob_mark): Check the 7-bit type tag and ignore those
whose type tag is not that of a SMOB in order to cleanly handle
free-list objects (this fixes a bug which showed up on SPARC64).
Also, don't mark & push ADDR itself.
(scm_gc_mark): Moved the definition and undefinition of
`CURRENT_MARK_PTR' and `CURRENT_MARK_LIMIT' here.

* libguile/mallocs.c (malloc_free): Removed.
(scm_init_mallocs): Don't invoke `scm_set_smob_free ()' because the
memory allocated by `scm_gc_malloc ()' will automatically be freed.
Furthermore, `malloc_free ()' used to invoke `free ()' instead of
`scm_gc_free ()' which is incorrect.
git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-25
* libguile/gc.c (finalizer_trampoline): Don't use `scm_call_2 ()' to
invoke the finalizer: directly call the C function instead.
(scm_gc_register_finalizer): Don't create a real subr with
`scm_c_make_gsubr ()': simply convert the C function pointer to an
`SCM' object instead.

* libguile/environments.c (scm_make_environment): Use
`SCM_RETURN_NEWSMOB' instead of `scm_cell'.

(scm_hash_fn_create_handle_x): Explicitly mention that we don't support
weak alist vectors.
(scm_internal_hash_fold): Handle weak pairs within buckets.
* libguile/modules.c (scm_module_reverse_lookup): Handle weak alists
(currently, don't do anything if a NULL pair is met).
