I saw this, something was broken for a short period for c++.  The "Fix"
is to install a new c++ compiler, i did:
cd src/gnu/usr.bin/gcc3
make USETOOLS=no clean
make USETOOLS=no
as root:
make USETOOLS=no install
make USETOOLS=no clean

But your mileage will vary, and it's not the cleanest way to do it, as
it does the build within the source tree, but if you need a working
system...

Alternatively download a new comp.tgz from releng.nb.org, and untar that
over your current install, then try your normal build method.  I think
the build in:
ftp://releng.netbsd.org/pub/NetBSD-daily/current/200403030000/i386/
is safe, but I can't remember when the bug was fixed.
