I have problem with the tests in HTTP-Server-Simple-0.44.

I am using:

• Strawberry-perl-5.12.2.0
• Perl 5, version 12, subversion 2 (v5.12.2) built for MSWin32-x86-multi-thread
• Windows 7 Home Premium with Service Pack 1

This is setup_listener from HTTP-Server-Simple-0.44/lib/HTTP/Server/Simple.pm

sub setup_listener {
    my $self = shift;

    my $tcp = getprotobyname('tcp');
    socket( HTTPDaemon, PF_INET, SOCK_STREAM, $tcp ) or croak "socket:
+ $!";
    setsockopt( HTTPDaemon, SOL_SOCKET, SO_REUSEADDR, pack( "l", 1 ) )
        or warn "setsockopt: $!";
    bind( HTTPDaemon,
        sockaddr_in(
            $self->port(),
            (   $self->host
                ? inet_aton( $self->host )
                : INADDR_ANY
            )
        )
        )
        or croak "bind to @{[$self->host||'*']}:@{[$self->port]}: $!";
    listen( HTTPDaemon, SOMAXCONN ) or croak "listen: $!";
}

When running some of tests, $self->host is undefined and the call to listen does not return (and sometimes get Windows 7 in blocked state). ($self->host with the value '0.0.0.0' used by Plack does also not work.)

Adding this before bind is a workaround

    $self->host('localhost') if ! defined $self->host;
    $self->host('localhost') if  $self->host eq '0.0.0.0';

Is this a bug in Windows or what is a proper solution?
