Build failure with today's svn

I just tried to build svn version 6836 on an i686-linux box using
gcc-4.1.1.  The last version I built was:  GNU DDD 3.3.12-test2
(i686-pc-linux-gnu).  

I ran ./configure; make

and after a while got:

make[2]: Entering directory `/home/ronis/Project/notar/ddd/ddd'
if /usr/bin/g++ -DHAVE_CONFIG_H -I. -I. -I.  -I./..

        then mv -f ".deps/VSLRead.Tpo" ".deps/VSLRead.Po"; else rm -f
".deps/VSLRead.Tpo"; exit 1; fi
