Actually I now get this at the beginning of the configure run, using a 
ramfs.ifs volume for $TMPDIR,

[K:\usr\local\src\ffmpeg.obj]sh ../ffmpeg/configure --enable-gpl 
--disable-doc --samples=/usr/local/share/fate-suite --cpu=i686 
--extra-libs=-lpoll --prefix='r:/tmp/ffmpeg' --disable-static 
--enable-shared
ln: failed to create symbolic link `R:/tmp/name_VJhuEZNf': Operation not 
supported on socket

I'll have to file a bug at Netlabs
