I tried to get -current working (for the userland). I pulled the source
via CVS as explained in the documentation, and make obj && make build. I
get this, is it known or "normal"?

c++ -O  -Werror   -I/usr/include/g++
-I/usr/src/gnu/lib/libstdc++/../../dist/libstdc++ -c
/usr/src/gnu/lib/libstdc++/../../dist/libio/isgetsb.cc
