	The following changes avoid polluting global namespace with the
	`enable' and `disable' identifiers, because some platforms define
	in their system headers symbols with global scope that go by those
	names.

	* breakpoint.h (enum enable_state): Rename from `enum enable'.
	Also rename all the enum members to have the "bp_" prefix.
	(struct breakpoint): Rename the `enable' member to `enable_state'.
	(enum bpdisp): Rename all members to have the "disp_" prefix.

	* breakpoint.c: All users of `enum enable' and `enum bpdisp'
	changed.
	(args_for_catchpoint_enable): Rename the `enable' member to
	`enable_p'.  All users changed.

	* tracepoint.h (enum enable): Remove.
	(struct tracepoint): The member `enabled' is now `int enabled_p'.

	* tracepoint.c: All users of the `enabled' member changed.

	* printcmd.c (struct display): The `status' member is now an int.

	* memattr.h (struct mem_region): Rename the `status' member to
	`enabled_p'.
	(enum enable): Remove.

	* memattr.c: Change all users of the `status' member of struct
	mem_region to use `enabled_p' instead.

	* infcmd.c (run_stack_dummy): Use disp_del instead of del.

	* go32-nat.c: Remove the kludgey work-around for conflicts between
	<dos.h> and "breakpoint.h".
	* tui/tuiSourceWin.c: Use disp_del instead of del.

	* tui/tuiSource.c: Use disp_del instead of del.

	* tui/tuiDisassem.c: Use disp_del instead of del.
