Porting the libstdc++ to L4env is a bit complicated. To determine
all additions we made you can try

  cd l4/pkg/libstdc++/contrib/libstdc++-v3
  cvs -q diff -r1.1.1.1 -rHEAD

(use the libstdc++ package from our remote cvs)

libstdc++-v3 should work with gcc-3.2 and gcc-3.3. libstdc++-6 was the
first try to get libstdc++ work with gcc-3.4, but it is currently broken.

Have a look at drops-gcc, it must be able to build valid L4env binaries
when passing no further parameters, (e.g. drops-gcc main.c _must_ work).
