This is one of those little chores in managing a long-lived C++ project: standard C headers like stdio.h and math.h now have their own place in the C++ standard as resp. cstdio, cmath, and so on. In this branch the #include names are updated for the util/ subdirectory; more branches to follow. C++11 adds cstdint, but to support compilation with the previous standard, that change is left for later.
