[Lib2geom-devel] Strange warning in interval.h and rect.h

[Jasper v. de G. <th....@hc...>]

I get the warnings below when compiling Inkscape, as I'm not completely 
sure what the code is meant to do I don't feel comfortable "fixing" it, 
but it looks like it could be a bug, anyone care to take a closer look?
