Browse source 
* libguile/dynstack.h:
* libguile/dynstack.c (PROMPT_FP, PROMPT_SP):
  (scm_dynstack_push_prompt, scm_dynstack_find_prompt): Prompts on the
  dynstack are recorded as offsets from the base stack address in this
  thread.

* libguile/eval.c (eval):
* libguile/stacks.c (find_prompt, narrow_stack):
* libguile/throw.c (pre_init_catch):
