Some warnings related with printf and derivates.

[GoogleCodeExporter]

I've noticed some warnings related with an "incorrect" use of printf and
derivates. Could you fix that issue aplying the next patch?

1535c1535
<     puts(buffer);

---
>     printf(buffer);
1545c1545
<     fputs(buffer, stderr);

---
>     fprintf(stderr, buffer);
