It's Ok - I have found the problem. I had another time.h in the include path
which was being found prior to the DJGPP one. The reason that example three
did not cause a problem was because I had already solved the problem without
knowing it by the time I tried that! At least I know what is going on now,
pity I did not work it out 5 mins earlier!
