Ah right, I'm daft, the backslash is escaping the dollarsign.

I don't think there's a really good means of dealing with this sort of
usecase to be honest, you could work around it for now by doing
something like:

	#set cpath = "c:\\%s\\%s" % ($p1, $p2)
	\#config_file   "$cpath"

Less than ideal, I agree, but will at least get you going until I 
have time to dig into the compiler code
