Bug 269

When NS_LOG is set to '*=level_all|prefix_func|prefix_time' infinite recursion occurs until the program crashes. Simulator::Now calls NS_LOG_FUNCTION_NOARGS which in turn calls Simulator::Now. The same happens for Simulator::GetImpl. This was introduced in revision 3469:9e763021e045.

Commenting out the following lines solves the problem.
