🚀 go-pugleaf

Here is a transcript demonstrating the problem.  Note the following commands
work fine on the sun4os4 port.  Also, for the Ncube port I am working on, the
command "info frame <absolute address>" works but yields less information about
the frame than if you specify the frame number instead.  This appears to be the
case because parse_frame_specification() calls create_new_frame() instead of
returning fid.  I do not understand why fid isn't just returned in all cases.

(gdb) info frame
Stack level 2, frame at 0xefffe84:
 pc = 0x22d8 in bar (t.c line 23); saved pc 0x22be
 called by frame at 0xefffe94, caller of frame at 0xefffe74
 Arglist at 0xefffe84, args: c=2
 Previous frame's sp is 0xefffe8c
 Saved registers:
  d2 at 0xefffe7c, d3 at 0xefffe80, fp at 0xefffe84, pc at 0xefffe88
(gdb) info frame 0xefffe84
Error reading memory address 0x0: I/O error (5).
