compilation problems using clang: boost-libs

Hi!

Please tell me if this is the wrong list to ask such questions.

I'm building various programs on NetBSD/amd64 using clang, currently
r153935, with c++ standard libraries from gcc-4.5.3.

This particular build failure is for boost-libs-1.49.0, and it looks like this:

Is this
http://llvm.org/bugs/show_bug.cgi?id=11309
?

Is there a patch available (I guess for libstdc++)?

Thanks,
