Modified files:
        guile-core/libguile: ChangeLog gc.c init.c root.c root.h 

Log message:
        * root.h (scm_root_state): removed the continuation_stack and
        continuation_stack_ptr members, which have no apparent purpose.
        (scm_continuation_stack, scm_continuation_stack_ptr): #defines
        removed.
        * root.c (root_mark), init.c (restart_stack, start_stack), gc
        (scm_igc): remove all references to contination_stack and
        continuation_stack_ptr, avoiding allocation of a vector and
        useless processing during gc.
