[PATCH] Replace some literal consts with enums.

[Michael Snyder <msnyder@cygnus.com>]

2002-01-31  Michael Snyder  <msnyder@redhat.com>

	* symfile.h (enum overlay_debugging_state): 
	Define enum constant values for overlay mode.
	* symfile.c (overlay_debugging): Use enums instead of literals.
	(overlay_is_mapped, overlay_auto_command, 
	overlay_manual_command): Ditto.
