glibc + nptl compile fail on x86-64

Has anyone been able to get NPTL working on x86-64?  I'm failing to
build glibc with the following error:

I'm running Suse 8.2 x86-64 beta on a dual Opteron, upgraded to kernel
2.6.0-test1.

gcc & glibc fresh from CVS 2003-07-17.
nptl-0.53

I added '#include <linux/compiler.h>' prior to all other includes in
linux-2.6.0-test1/include/linux/sysctl.h.


gcc configured like this:
../gcc/configure --prefix=/opt/kernel/gcc-bootstrap --disable-shared \
--enable-languages=c,c++

glibc configured like this:
CC=/opt/kernel/gcc-bootstrap/bin/x86_64-unknown-linux-gnu-gcc \
../glibc/libc/configure --prefix=/opt/lib64 --disable-profile \
--enable-add-ons=nptl --with-__thread --enable-kernel=current \
--with-tls --with-headers=/opt/kernel/linux-2.6.0-test1/include

If anyone has successfully built please let me know what toolchain
versions appear to work (or if my quest is futile).  Any help much
appreciated.
