	I've downloaded this time the file ecos-trunk-full.tar.bz2 from
ecoscentric (I don't have cvs access at work, but it is supposed to be a
weekly snapshot from the CVS, right?), Extract it in /opt, made a
$HOME/ecos-build directory, gone into it, run /opt/ecos/configure
--prefix=/usr/local/ecos, run make. And this is the result:

[root@software ecos-build]# make

	Why? (almost the same as with ecos-2.0 tarball)
