Annoyingly, C++ compilers don't enable these macros per default as they
are in the C99 standard. Grrr. You have to define
#define _ISOC99_SOURCE
#define __STDC_LIMIT_MACROS
#define __STDC_CONSTANT_MACROS
#define __STDC_FORMAT_MACROS
before you include any of the header files. util.h or so might be a good
place to add these defines. (For the printf macros to work, you probably
only need the first and the last define, but I the others are probably
handy too).
