getopt errors

[Sebastiaan Koppe via D.gnu]

This code:

	bool time;
	string fileIn;
	string fileOut;

	auto helpInformation = getopt(
		args,
		"time", "Show timing information", &time,
		"i|input", "Input file (defaults to stdin)", &fileIn,
		"o|output", "Output file (defaults to stdout)", &fileOut
	);

	if (helpInformation.helpWanted)
	{
		defaultGetoptPrinter("ECMAScript 5 
minifier.\n\nUsage:\t"~baseName(args[0])~" 
[OPTIONS]\n\nOptions:\n", helpInformation.options);
		return 1;
	}

on gdc 5.3.0-1 Gives me:
