+//   printf("xyz:%" PRId64, value);
+// The "d" in the macro corresponds to %d; you can also use PRIu64 etc.
+//
+// For wide strings, prepend "Wide" to the macro:
+//   int64_t value;
+//   StringPrintf(L"xyz: %" WidePRId64, value);
+//
+// To print a size_t value in a portable way:
+//   size_t size;
+//   printf("xyz: %" PRIuS, size);
+// The "u" in the macro corresponds to %u, and S is for "size".
