	* parse.c: Fix problem on Win32 where the automagic prefix
	replacement logic didn't work. I don't know what change had 
	broken it.
	(pathnamecmp): New Win32-only function. Compares two file
	paths case insensitively and treating backslashes as equal to
	slashes.
	(parse_line): Use it instead of g_ascii_strcasecmp().
