Global constructor time is too late, by this time dependent libraries
will have been loaded and initialized, which will crash and burn if some
of them are Windows dlls. Also you need the environment and command line
setup before the global constructors are run. You also need to setup the
process stack, which you can't do inside a constructor that you have to
return from.
