(void *) in order to avoid an aliasing warning; thanks to Bruce Korb.) * stackchk.h (SCM_STACK_OVERFLOW_P): Use SCM_STACK_PTR. * threads.c (suspend, launch_thread, scm_threads_mark_stacks): Use SCM_STACK_PTR. * threads.c (scm_threads_mark_stacks): Bugfix: Changed thread->base --> t->base. * eval.c (SCM_CEVAL): Don't cast argument of SCM_STACK_OVERFLOW_P.
