[ob] stack.c cleanups

[Andrew Cagney <cagney at gnu dot org>]

This cleans up stack.c a little deleting:

- long-ago #if 0 code
- DEPRECATED_STREQ
- a stray frame_relative_level

committed,
Andrew

2004-05-01  Andrew Cagney  <cagney@redhat.com>

	* stack.c (select_frame_command): Delete call to
	frame_relative_level.
	(print_frame, set_backtrace_limit_command, backtrace_limit_info):
	Delete #if0 code.
	(frame_info): Do not print FRAMELESS.
	(print_block_frame_labels): Replace DEPRECATED_STREQ.
	(catch_info): Delete #if0 code.
