I am using the l4env_freebsd mode (cannot use dietlibc because I need
STL). Do I understand correctly that RTTI and exceptions can be used
with libstdc++?

The next issue I have stumbled upon is that pthread_yield() can't be
found. Other pthread functions work fine (I do include <pthread.h> and
pthread.h is found by the include paths).

Thanks in advance,
