+       Don't use GCC extensions to allocate space for debugging frames.
+       (Here he goes again!  Why do we put up with this?!)
+       * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
+       an scm_debug_info structure, not an in-line array of them.  Add
+       'info' member, to say how many vect elements we've used, for eval
+       frames.
+       * eval.c (SCM_CEVAL): Use alloca to allocate space for vect.  Use
+       a new variable debug_info_end to mark the end of vect, instead of
+       the address of the 'info' pointer itself.
+       [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
+       &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
+       (SCM_APPLY): Explicitly allocate space for debug.vect. 
+       * debug.c (scm_m_start_stack): Same, for vframe.vect.
+       * stacks.c: Adjusted for new debug frame structure.
+       (RELOC_INFO, RELOC_FRAME): New macros.
+       (stack_depth, read_frames): Use them, and new scm_debug_frame
+       element 'info', instead of magically knowing that eval frames have
+       an info pointer sitting after vect.
+       (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
+       RELOC_FRAME.
+       (scm_init_stacks): Formatting tweaks.

        Give GCC more control flow information, so it can be sure that
