gettimeofday() broken in MiNTLib?

[Tamminen Eero <t150315@proffa.cc.tut.fi>]

When I compile the gettimeofday() code at the bottom, only timeval
struct member tv_sec changes and in step of two!!! The interval seems
to be about one second so it's also bogus besides not being updated
at 200hz interval as I would have thought. This throws off my W Jewel
game timing a 'bit'...

I got MiNTlibs PL46 and otherwise they seem to work just perfectly.
Do you got any clues to what might be wrong?

    now.tv_sec, now.tv_usec);

  return 0;
