it depends.
If if you need to use libraries that link against dielibc (my case) tou 
cannot use this features, my case was with L4VFS.
But if you are using libraries and servers that are fully compatible 
with C++, you just need to:

1 - in your makefile, use the l4env_freebsd mode (MODE = l4env_freebsd)
2 - link your app with stdc++ (LIBS += -lstdc++)
3 - use the flags -nostdlib so that your program doesn't link with the 
library from the system (CXXFLAGS = -nostdlib)

Just following the cxx_hello example...

hope i've helped.
