When building the following (reduced by hand - I hope I didn't 
take out something useful when doing so):

import std.stdio;
import std.getopt;

int main(string[] args)
{
	string apiKey;
	string startCode;
	bool reverseOrder=false;
	bool noReverse=false;

	auto helpInformation = getopt(
		args,
		"apikey|k",    "specify API key directly",&apiKey,
		"startcode|c", "start begining from specified code",&startCode,
		"reverse|r","reverse sort order",&reverseOrder,
		"noreverse|n","don't reverse sort order",&noReverse
	);
	if (helpInformation.helpWanted)
	{
		defaultGetoptPrinter(	"downloader tool", 
helpInformation.options);
		return(1);
	}
}

I get the following errors under LDC (this is LDC beta, but same 
problem under master) although the code compiles fine under DMD.

Am I doing something wrong?

The help generating feature of std.getopt is new in 2.067. Use 
branch "merge-2.067" for that. Otherwise, don't use std.getopt's 
help generation just yet.
