| Ugh. There is an unintended compiler / glibc #include glitch caused by |
| combining the u64 type an %llu in format strings, necessitating a workaround. |
| |
| In essence, the compiler is always looking for 'unsigned long long' for %llu. |
| On 32-bit systems, the u64 type (aliased to uint64_t) is expanded to |
| 'unsigned long long' in <bits/types.h>, so everything checks out. |
| |
| But on 64-bit systems, it is #ifdef'ed in the same file as 'unsigned long'. |
| Now, it only happens in circumstances where the type happens to have the |
| expected bit width, *but* the compiler does not know that... and complains |
| about 'unsigned long' being unsafe to pass to %llu. |
