> 	is null.	

Are you sure this patch is against 6.1 or a current GDB?  The function 
h8300_frame_init_saved_regs has a void return type.

Also, you might want to read over:
   Post GDB 6.2, require new frame code
   http://sources.redhat.com/ml/gdb/2004-06/msg00199.html
As this will affect the h8/300.
