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.
