It seems like FILE* (fopen) might be 50% faster in some cases, and you might get another 10% if you use ReadFile to do overlapped File IO. (I'm assuming no SSD's here)
However, is 60% performance enough to meet your target? If not, you might have to look for other types of performance improvements. Personally, I haven't encountered a Code Jam problem yet where reading the input took enough resources to warrant any consideration of alternate tool-chains. (And I've been using C# mostly, which should be even slower...) Which problem are you looking at again?
