That's from the WIN32 build of raptor that is used in a couple of
products and some other places.

Nice; it is a pretty general library using standard C libraries and
little more.

rdfdump is the raptor tool.

The example4 redland program is a pretty-much standalone RDF redland
program that I've been meaning to make more prominent if I can think
of a good name for it - rdfdb?  rdftool?

I understand WIN32 dlls needs some extra support for declaring
exported symbols, so I'm not confident it'll necessarily work.
