It's up to you.  The downside of the separate upload is that people
will need to be told to download the second archive, and relied upon
to read those instructions.  But we could try that and see how many
people complain about colors missing from their tool bar.

It needs to be hacked to build on Windows, because it originally
assumed X Window system only.

It's already hacked, look at the diffs.

I don't have time to build the newer libXpm; if you do, please feel
free.  FWIW, I don't see a compelling need, except to have the latest
and perhaps submit patches upstream, so that future releases build on
Windows out of the box.
