* libguile/init.h: * libguile/init.c (scm_i_init_guile): Change arg to this internal function from SCM_STACKITEM* to void*. Actually it's a struct GC_stack_base*. * libguile/bdw-gc.h: Don't do pthread redirects, because we don't want to affect applications' pthread_* bindings. * libguile/pthread-threads.h (scm_i_pthread_create) (scm_i_pthread_detach, scm_i_pthread_exit, scm_i_pthread_cancel) (scm_i_pthread_sigmask): Do pthread redirects here, in this internal header. * libguile/threads.h: Remove declaration of internal scm_i_with_guile_and_parent. Remove declaration of undefined scm_threads_init_first_thread. Make declaration of internal scm_threads_prehistory actually internal, and take a void* (actually a struct GC_stack_base*). * libguile/threads.c (GC_get_stack_base): Implement a shim if this function is unavailable, and fold in the implementations of get_thread_stack_base. (GC_call_with_stack_base): Actually implement. (guilify_self_1): Take a GC_stack_base* as an arg. (scm_i_init_thread_for_guile): Likewise, and set up libgc for registration of other threads. (scm_init_guile): Use GC_get_stack_base instead of our own guesswork. (with_guile_and_parent, scm_i_with_guile_and_parent): Rework to trampoline through a GC_call_with_stack_base. (scm_threads_prehistory): Pass the "base" arg on to guilify_self_1.
