[cc65] macro woes

ca65 macros just don't like me. How do I check if an argument is a
string? I want a macro that can either take a string or a label:

	.macro printf str, arg1, arg2, arg3, arg4, arg5, arg6, arg7, arg8, arg9

	.local arglist
	.local string

	ldax #arglist
	jsr console_printf

	.rodata

	.if (.match(.left (1, str), '"'))
string:
	    .asciiz str
arglist:
	    .addr string
	.else
arglist:
	    .addr str
	.endif

	printfargs arg1, arg2, arg3, arg4, arg5, arg6, arg7, arg8, arg9

	.code

	.endmacro

'"' never matches, " and \" gives me syntax errors instead. In
printfargs I have the same problem when I try to match '$'...

Also, would it be possible for ca65 to spit out the expanded macro
when an error occurs inside it? It would also help if listings had the
expanded macro code.
