[cc65] .macro related error

The situation:

file: ui.i
-----------------
.import ui_system_status_code
.macro ui_status status_code, status_msg
	ldx # status_code
.ifnblank	status_msg
	lda #< status_msg
	ldy #> status_msg
.endif
	jsr ui_system_status_code
.endmacro


file: status.i
-------------------
.enum
	SCANNING_DEVICES
	LOADING_DRIVERS
.endenum


file: load_drivers.s
------------------------
.include "../ui.i"
.include "../status.i"
[...]
	ui_status (LOADING_DRIVERS, msg_status_loading_drivers)
[...]


Generates upon building:

ui.i(6): Note: Macro was defined here
load_drivers.s(25): Error: Unexpected trailing garbage characters
ui.i(8): Note: Macro was defined here
load_drivers.s(25): Note: Macro parameter came from here
load_drivers.s(25): Error: Unexpected trailing garbage characters
ui.i(9): Note: Macro was defined here
load_drivers.s(25): Note: Macro parameter came from here

But when I invoke the same macro without parentheses, it seem to compile fine. What is the problem with parentheses here? Or is it the combination with .enum? causing troubles?
