(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.
