Hi!

Thanks for your bug report! (and sorry for the delay in the answer!)  

I've changed the code, and also make some other changes that Jose K. ask 
me... Indeed, there is no big deal, I just separated   WebDAV and 
extension methods modifications. Now, we may chose between them using 
"--with-dav" and "--with-extensions" options...  For those who wants 
just one of them.. :)
The code is available in the same URL 
http://gnome.inrialpes.fr:1959/src/libwwwDAV.tar.gz

Best regards,

Manuele
