./configure --prefix=/usr/local/gcc4.0 --with-system-zlib --enable-languages=c,c++
We never use "./configure". It is supposed to work, but since we never use this ourselves, it is often accidentally broken. Instead, you should do something like
cd ..
mkdir build
cd build
../gcc/configure ...
You probably have to delete everything in the source tree that was created by your broken configure/build before this will work. This may be tricky, but if you delete everything that "cvs update" complains about, then you should be OK. If you configure in a different directory, it is trivial to delete a broken build. Also, this makes it easy to build multiple cross compilers from a single source tree, which many of us often need to do.
gcc-bugs is mainly for bugzilla output nowadays. It isn't the best place to ask questions.
