This code from Converter.pm:

     if (defined($self->get_conf('SUBDIR')) and $output_file ne '') {
       my $dir = File::Spec->canonpath($self->get_conf('SUBDIR'));
       print STDERR "DFD SUBDIR: '$dir'\n";
       $output_file = join('/', ($dir, $output_file));

calls File::Spec->canonpath.  I'm pretty sure it returns file names
with backslashes on Windows, evidently because that's the "canonical"
form of file names there.

So we could have a customized version of canonpath, which on Windows
mirrors all backslashes to forward slashes.
