     The library is only tested with gcc-3.4 and 4.0 on Linux. On other POSIX platforms with a BSD
     Socket API, the library should be usable, possibly with some tweaking (except for the Scheduler,

+    If SENF is compiled in debug mode (SENF_DEBUG is defined), exception messages will
+    automatically include a stack backtrace. For this to work, you need to add the -rdynamic option
+    to all link commands. This feature depends on gcc and the GNU-libc.
+
+    It is <B>very important</B> that both the SENF library and the application using it are either
+    compiled with or without this compiler switch (-DSENF_DEBUG). Otherwise, the compiler will emit
+    error messages which might be hard to debug.
