The log4cplus::initialize() function is there to initialize the whole
log4cplus library. In most usual cases, on both Windows and Unix--like
platforms, it will be called for you. Unfortunately, there are cases
when it will not be called automatically. This can happen if you are
using static library log4cplus and static C and C++ run time
libraries. It is safe to call the function multiple times before you
use anything else from log4cplus. It is not safe to call the function
from different threads, there is no locking. The assumption is that,
at the worst case, you will call the function at the top of main().
