How does this look?

gdb/ChangeLog:
2005-11-19  Jim Blandy  <jimb@redhat.com>

	* tracepoint.c (memrange_absolute): New enum constant.
	(struct memrange, memrange_cmp, add_memrange, collect_symbol,
	stringify_collection_list, encode_actions): Use it instead of '-1'
	to indicate an fixed-address memory range.
	(Suggested by Eli Zaretskii.)
