I have tried to compile GCC 4.7.0 under Ubuntu 11.10 64 bit
> with the following configuration parameters:
configure -v --enable-languages=c,c++,fortran

What about checking this at : http://gcc.gnu.org/onlinedocs/libstdc++/manual/debug.html
I get this error: mv: cannot stat `Makefile': No such file or directory
Usually this means that the configure failed in some directory and no Makefile was created...
make[7]: Entering directory `/home/username/Desktop/gcc-build/x86_64-unknown-linux-gnu/libstdc++-v3/src/debug'
Here the directory is a 'debug' subdir in the usual: $target/libstdc++-v3/src Knowing that eglibc for Ubuntu has those 'libc6-dbg_*.deb' install packages, one can only wonder what are they for and whether they would be required to be used with a debug-enabled 'libstdc++' ? That they are obligatory if one wants a debug -enabled libstdc++ sounds quite obvious for me. Are you sure that the 'libc6-dbg_*.deb' package(s) is/are installed?
With gcc 4.6.2 all works well.
Maybe with gcc-4.6.2 accepts the usual non-debug eglibc to be linked with a debug-enabled libstdc++ ?
