libstdc++ compile problem in head


I get this error when compiling gcc cvs head.
My Linux is using a recent version of glibc with NPTL.
I am not sure if NPTL causes the problem.
Also --disable-werror and passing -DWERROR=-Wno-error do not disable the warnings.

This is how I compile glibc:
../glibc-cvs/libc/configure \
         --prefix=/usr   \
         --sysconfdir=/etc       \
         --localstatedir=/var    \
         --infodir=/usr/share/info       \
         --mandir=/usr/share/man \
         --enable-sanity-checks  \
         --enable-add-ons=nptl \
         --enable-all-warnings \
         --with-tls \
         --with-gmp=/usr \
