It didn't work for me...

I've been rebuilding my system a couple of times during
the last two weeks, always usingup-to-date sources from
cvsup.no.openbsd.org.

After building this system ("build.sh -x -u distribution;
build.sh install=/"):
NetBSD coffee.please 1.6ZK NetBSD 1.6ZK (GENERIC) #1: Sun Feb 29 01:34:29 GMT 2004  root@coffee.please:/usr/obj/sys/arch/i386/compile/GENERIC i386

... a reboot and an immidiate rebuild ("build.sh tools
kernel=GENERIC") triggers the same problem.  Now, a simple
hello world in C++ does this:

$ cat test.cc
#include <iostream>

int main()
{
        std::cout << "Hello world" << std::endl;
}
$ c++ test.cc
/usr/lib/libstdc++.so: undefined reference to `_Unwind_GetIP'
/usr/lib/libstdc++.so: undefined reference to `_Unwind_Resume_or_Rethrow'
/usr/lib/libstdc++.so: undefined reference to `_Unwind_GetRegionStart'
/usr/lib/libstdc++.so: undefined reference to `_Unwind_Resume'
/usr/lib/libstdc++.so: undefined reference to `_Unwind_DeleteException'
/usr/lib/libstdc++.so: undefined reference to `_Unwind_RaiseException'
/usr/lib/libstdc++.so: undefined reference to `_Unwind_SetIP'
/usr/lib/libstdc++.so: undefined reference to `_Unwind_GetTextRelBase'
/usr/lib/libstdc++.so: undefined reference to `_Unwind_GetLanguageSpecificData'
/usr/lib/libstdc++.so: undefined reference to `_Unwind_SetGR'
/usr/lib/libstdc++.so: undefined reference to `_Unwind_GetDataRelBase'


I tried replacing the /usr/lib/libgcc* files with the
corresponding files in the snapshot at
ftp://releng.netbsd.org/pub/NetBSD-daily/current/200402250000/i386/binary/sets/ 
without success (problem remains).

Do you think the solution might be to pick an older snapshot?
