heh, I should learn not to reply in a hurry, just before going out ... I had not noticed that 'value' was declared with an 'sized type' of uint64_t, so using PRIu64 should be fine. Well, except that you may have to add a 'fallback' definition of PRIu64 to one of the 'compat/mingw.h', 'compat/msvc.h' or 'git-compat-util.h' header files. (see e.g. PRId64 at compat/mingw.h:429).
