* gc.c (stack_end_address): new function to obtain stack end address.

2004-12-13T09:58:12+00:00

  stack_end_address calls __builtin_frame_address(0) to obtain the
  frame pointer of a stack frame of stack_end_address.  The address
  is the stack pointer of the caller's stack frame.
  (SET_STACK_END): use stack_end_address.
  This makes the conservative garbage collector to scan a stack frame
  of the garbage_collect function itself.  This is required because
  callee-save registers may be stored in the frame.
