loads the DLL. This is different from LibMain which gets
called only once when the DLL is loaded. The only time this
is critical is when you are using shared data sections.
If you are using shared data sections for statically
allocated data, you will need to be careful to initialize it
only once. Check your code carefully.
Certain one-time initializations may now need to be done for
each process that attaches. You may also not need code from
your original LibMain because the operating system may now
be doing it for you.
