Comment:
After 10 days with no answer on the mailing list, since this only requires a single function to copy one file, how about shelling out to /bin/cp? eg
```
#include <sys/wait.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>

static int qcopy_file_preserving(const char *src, const char *dst)
{
        int stat_loc;
        pid_t pid = fork();
        if (pid < 0) {
                perror("fork");
                return -1;
        }
        if (pid == 0) {
                execl("/bin/cp", "--", src, dst, (void *)0);
                exit(1);
        }
        if (pid != waitpid(pid, &stat_loc, 0)) {
                perror("waitpid");
                return -1;
        }
        if (!(WIFEXITED(stat_loc) && WEXITSTATUS(stat_loc) == 0)) {
                return -1;
        }
        return 0;
}
```

should work fine until upstream makes a new release, right?
