Hi Stephen,

declares two variables of type int, j and str1; the pre-existing
char * str1 isn't used. This causes compiler warnings. Declaring j
outside the loop fixes everything.
To enable automated source extraction, separate the text following the
code.

Since these are two completely unrelated things, I'd prefer 2 patches.
If you resend this one without the subsection heading, I'll apply it.
Thanks,
Alex
