* frame.c (get_prev_frame): Move disabled inside_entry_func to
	before code inhibiting repeated unwind attempts.  Add to
	commentary on that test's problems.
	* blockframe.c (inside_main_func): Look for "main" in the minimal
	symbol table.
	* d10v-tdep.c (d10v_frame_this_id): Delete check that frames are
	identical.
