This is to let dll code register functions with atexit.  Previously atexit was
defined as noop stub because calls to atexit from the dll would end up
registering functions in the app's atexit table. Dlls now use their own private
atexit table (hence calls to malloc, free and errno) and calls to atexit get
thunked to __dllonexit which fills in the private atexit table.  The fflush is
there to fix a bug that resulted when dll detached before output buffers were
flushed.  This happened with redirected output.
