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.
like to stay that way. If we want, we can turn it off by default
when we make the stable release, but I caught a lot of bugs this
way. Accomodate libguile-ltdl -- therea are some ltdl things that
are commented out now INCLTDL and LIBLTDL. I think we may not
need them anymore, but I'll leave them until we're sure. We also
killed off the libltdl dir and related options including the
AC_CONFIG_SUBDIRS. I also added some explicit tests for some
headers and functions that weren't listed but were in
scmconfig.h.in. though this may have been unnecessary.
scm_lt_dlopenext, and scm_lt_dlerror.
(sysdep_dynl_unlink): switch to scm_lt_dlhandle, scm_lt_dlclose,
and scm_lt_dlerror.
(sysdep_dynl_func): switch to scm_lt_dlhandle, scm_lt_dlsym,
and scm_lt_dlerror.
(sysdep_dynl_init): switch to scm_lt_dlinit();
* raw-ltdl.c: Remove custom realloc. (#define rpl_realloc
realloc). You can't define realloc like this unless you also
define malloc. This is a quick hack for now; we may want
something cleaner later.
(memcpy): coerce ptrs to (char *) before copying characters
through them -- I can't recall for sure, but I believe this was
causing an overrun error at times.
(realloc): commented out -- as mentioned above, you can't define
your own malloc unless you know enough about the malloc in use to
be able to tell how big the src ptr is. The disabled code
incorrectly used the *destination* ptr to decide how much to copy.
This sometimes results in out-of-bound accesses which cause
segfaults.
(tryall_dlopen_module): check to be sure (dirname_len > 0) before
testing first character against '/'.
(try_dlopen): check for feof(file) in read loop -- otherwise
infloop?
(scm_lt_dlopenext): remove unused variable file_found.
(LT_EOS_CHAR): moved here from guile-ltdl.h.

(LT_EOS_CHAR): moved here from guile-ltdl.h.
* scmsigs.c (got_signal): Removed.
(signal_handler_cells, signal_handler_threads): New.
(take_signal): Queue the cell of the signal for the specified
thread. Reset the signal handler on systems that don't have
sigaction.
(sys_deliver_signals): Removed.
(close_1): New.
(scm_sigaction_for_thread): Renamed from scm_sigaction and
extended to also set the thread of a signal and allocate a cell
for it. Keep the Scheme name "sigaction". Check that signum is
within range. Also, use SCM_VECTOR_REF instead of SCM_VELTS.
(scm_sigaction): Implement in terms of scm_sigaction_for_thread.
(scm_init_scmsigs): Allocate signal_handler_cells and
signal_handler_threads vectors.
* coop-threads.c (all_threads, scm_current_thread,
scm_all_threads, scm_i_thread_root): New.
(scm_threads_init): Add main thread to all_threads.
(scheme_launch_thread): Remove thread from all_threads when it
terminates.
(scm_call_with_new_thread): Initialize handle slot of coop_t
structure and add new thread to all_threads.
(scm_spawn_thread): Likewise.
