Ok.
Shouldn't it more correctly be:
const struct sum_struct null_num = {0, 0, 0, 0, 0, NULL};
Perhaps more readable, but in no way more correct.
Putting the const qualifier on that variable allows the const qualifier to be put on the "sum" parameter.
This allows the compiler to better optimize the code for the modules that call write_sum_head().
In any case for the purposes of porting RSYNC to Posix Threads means that this is not a thread specific variable.
