What autogen.sh for an alternative ContentProvider for dav:// scheme?

Hi all,

while I was trying with a fairly current master to open a WebDAV file as:

./soffice 
dav://192.168.1.80:8080/alfresco/webdav/Sites/davtest/documentLibrary/Lorem_ipsum.odt

I got the following warnings:

warn:ucb.ucp.gio:17565:1:ucb/source/ucp/gio/gio_content.cxx:400:

A log on the net told me the OPTIONS method the Alfresco server answered 
advertised itself as a WebDAV share.
The User-Agent on the http transaction was gvfs/1.20.3.

master was built with following autogen.sh input:

--with-lang='en-US' \
--enable-debug \
--enable-selective-debuginfo="sal/ offapi/ tools/ unotools/ sfx2/ 
ucbhelper/ ucb/"

OTOH, doing the same test on a LO 5.0 production build (5.0.0.5) I got 
no error and the content provider was the WebDAV ContentProvider, net 
log confirmed it (User-Agent was LibreOffice).

Is this due to a different configuration on LO 5.0.0.5 production build 
or is there a difference in ucb code?
