Bug fix for the CPAN module Archive::Zip. The error `IO error: seeking to rewrite local header : Illegal seek` happened when write to the STDOUT.

patch for Archive-Zip-Member.pm

# patch for Archive/Zip/Member.pm
# search the 'bitFlag' subroutine and replace it.
sub bitFlag {
    my $self = shift;

    # Set General Purpose Bit Flags according to the desiredCompressionLevel setting

    my $hasDataDescriptor = $self->hasDataDescriptor();
    if ( $self->desiredCompressionLevel == 1 || $self->desiredCompressionLevel == 2 ) {
        $self->{'bitFlag'} = DEFLATING_COMPRESSION_FAST | $hasDataDescriptor;
    } elsif ( $self->desiredCompressionLevel == 3 || $self->desiredCompressionLevel == 4
          || $self->desiredCompressionLevel == 5 || $self->desiredCompressionLevel == 6
          || $self->desiredCompressionLevel == 7 ) {
        $self->{'bitFlag'} = DEFLATING_COMPRESSION_NORMAL | $hasDataDescriptor;
    } elsif ( $self->desiredCompressionLevel == 8 || $self->desiredCompressionLevel == 9 ) {
        $self->{'bitFlag'} = DEFLATING_COMPRESSION_MAXIMUM | $hasDataDescriptor;
    }
    $self->{'bitFlag'};
