Обсуждение: prewarm compiler warnings

gcc-6.3.0 complains about this:

autoprewarm.c: In function ‘autoprewarm_main’:
autoprewarm.c:210:9: warning: variable ‘rc’ set but not used 
[-Wunused-but-set-variable]
    int   rc;

The warning comes only in master.

The warnings are a bit annoying; the attached silences them by removing 
those assignments.

Thanks,

Yeah, it's fairly new.  I noticed a couple of other places that could
use the same adjustment and pushed them all together.  (I used a cast to
void as all other places do that, which appeases Coverity about the
discrepancy.)
