* psyntax.ss (self-evaluating?): Removed. Guile now provides this
operator as a primitive procedure.
(build-data): Quote vectors (psyntax.ss requires this).
in output. (We normally *would* like also these expressions to be
quoted, but until Guile's native macros and syncase cooperates
better, it is less destructive not to quote.)
(self-evaluating?): Removed null? (In Guile, the empty list is not
self-evaluating).
(sc-chi): Export chi as sc-chi.
(external-macro): New syntax type.
* psyntax.pp: Regenerated.
* compile-psyntax.scm: Set expansion-eval-closure.
* syncase.scm: Set expansion-eval-closure to
the-syncase-eval-closure during booting so that variables are
created in the correct module.
(syncase): Set expansion-eval-closure.
(define-syntax define-syntax-public eval-when fluid-let-syntax
identifier-syntax let-syntax letrec-syntax syntax syntax-case
syntax-rules with-syntax include): Removed definitions (these are
created from within psyntax.pp).
Enable expansion of Guile macros during a syntax-case
transformation.

(define-syntax define-syntax-public eval-when fluid-let-syntax
identifier-syntax let-syntax letrec-syntax syntax syntax-case
syntax-rules with-syntax include): Removed definitions (these are
created from within psyntax.pp).
compute-new-list-of-methods): Use methods slot directly instead of
generic-function-methods.
(upgrade-generic-with-setter): Handle <extended-generic>:s.
(define-extended-generic): New syntax.
(make-extended-generic): New function.
* goops.c, goops.h (scm_class_extended_generic_with_setter): New
class.
(scm_compute_applicable_methods): Use scm_generic_function_methods.
* goops.c (scm_generic_function_methods): Support extended
generic functions.
* 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.
thread_admin_mutex in order not to risk being joined.
(scm_i_thread_put_to_sleep, scm_i_thread_wake_up): Keep
thread_admin_mutex locked during GC.
* pthread-threads.c, pthread-threads.h: Improvements to debugging
functions.
(thread_print): Print thread number as well as address of thread
structure.
(scm_join_thread): Bugfix.
(scm_lock_mutex, scm_try_mutex, scm_unlock_mutex,
scm_timed_wait_condition_variable, scm_signal_condition_variable,
scm_broadcast_condition_variable): Use the low-level API.
(scm_all_threads): Return copy of thread list (to prevent
unintended destruction).
(scm_threads_prehistory): Initialize heap_mutex of fake thread.
Simply lock a thread C API recursive mutex.
(SCM_NONREC_CRITICAL_SECTION_START,
SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
SCM_REC_CRITICAL_SECTION_END): Removed.
* eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with
direct calls to scm_rec_mutex_lock / unlock around the three calls
to scm_m_expand_body.
* eval.c, eval.h (promise_free): New function.
(scm_force): Rewritten; Now thread-safe; Removed
SCM_DEFER/ALLOW_INTS.
* pthread-threads.h: Added partially implemented plugin interface
for recursive mutexes. These are, for now, only intended to be
used internally within the Guile implementation.
* pthread-threads.c: New file.
* threads.c: Conditionally #include "pthread-threads.c".
* eval.c, eval.h (scm_makprom, scm_force): Rewritten to be
thread-safe;
* snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX,
SCM_GLOBAL_REC_MUTEX): New macros.
* eval.c, threads.c, threads.h, snarf.h: Rewrote critical section
macros---use mutexes instead.
* tags.h (SCM_IM_FUTURE): New tag.
* eval.c (scm_m_future): New primitive macro.
(SCM_CEVAL): Support futures.
(unmemocopy): Support unmemoization of futures.
* print.c (scm_isymnames): Name of future isym.
