Package: ftp.debian.org >From the gcc source package the libstdc++2.10-glibc2.1 package is still in unstable. From the egcs1.1 source package the libstdc++2.9-glibc2.1 package is in unstable. These packages cannot be built anymore on a glibc2.2/2.3 based system. Even no non-free packages depend on them. The binaries can still be fetched from potato or woody.
