I'm getting an error on SVN revision 17677. When I try to configure libxfce4util, I get "checking for C compiler default output file name... configure: error: C compiler cannot create executables". Attached is the config.log which has more context, but I'm not sure if any of it is useful.
Created attachment 314 config.log
This isn't an xfce problem. Make sure your autotools are up to date (automake 1.8+, autoconf 2.53+, libtool 1.5+) and rerun autogen.sh.
