On non-ELF systems, gcc will cause the main function to invoke a
function named __main. That function will use atexit to arrange to
run global destructors at program exit time. If you don't care about
global destructors, then provide a dummy version of the standard
atexit function. Some BSD libraries provide on_exit rather than
atexit, in which case your atexit function can simply call on_exit.
